40-303 1.39e-90

periplasmic sugar-binding domain of active transport systems that are members of the type 1 periplasmic binding protein (PBP1) superfamily; Periplasmic sugar-binding domain of active transport systems that are members of the type 1 periplasmic binding protein (PBP1) superfamily. The members of this family function as the primary receptors for chemotaxis and transport of many sugar based solutes in bacteria and archaea. The sugar binding domain is also homologous to the ligand-binding domain of eukaryotic receptors such as glutamate receptor (GluR) and DNA-binding transcriptional repressors such as LacI and GalR. Moreover, this periplasmic binding domain, also known as Venus flytrap domain, undergoes transition from an open to a closed conformational state upon the binding of ligands such as lactose, ribose, fructose, xylose, arabinose, galactose/glucose, and other sugars. This family also includes the periplasmic binding domain of autoinducer-2 (AI-2) receptors such as LsrB and LuxP which are highly homologous to periplasmic pentose/hexose sugar-binding proteins.

39-304 4.30e-69

periplasmic binding proteins specific to rhizopines; Periplasmic binding proteins specific to rhizopines, which are simple sugar-like compounds produced in the nodules induced by the symbiotic root nodule bacteria, such as Rhizobium and Sinorhizobium. Rhizopine-binding-like proteins from other bacteria are also included. Two inositol based rhizopine compounds are known to date: L-3-O-methly-scyllo-inosamine (3-O-MSI) and scyllo-inosamine. Bacterial strains that can metabolize rhizopine have a greater competitive advantage in nodulation and rhizopine synthesis is regulated by NifA/NtrA regulatory transcription activators which are maximally expressed at the onset of nitrogen fixation in bacteroids. The members of this group belong to the pentose/hexose sugar-binding protein family of the type 1 periplasmic binding protein superfamily.

periplasmic xylose-like sugar-binding component of the ABC-type transport systems; Periplasmic xylose-binding component of the ABC-type transport systems that belong to a family of pentose/hexose sugar-binding proteins of the type 1 periplasmic binding protein (PBP1) superfamily, which consists of two alpha/beta globular domains connected by a three-stranded hinge. This Venus flytrap-like domain undergoes a transition from an open to a closed conformational state upon ligand binding. Moreover, the periplasmic xylose-binding protein is homologous to the ligand-binding domain of eukaryotic receptors such as glutamate receptor (GluR) and DNA-binding transcriptional repressors such as LacI and GalR.

40-304 1.48e-41

monosaccharide ABC transporter substrate binding protein such as CUT2; Periplasmic sugar-binding component of uncharacterized ABC-type transport systems that are members of the pentose/hexose sugar-binding protein family of the type 1 periplasmic binding protein superfamily, which consists of two alpha/beta globular domains connected by a three-stranded hinge. This Venus flytrap-like domain undergoes transition from an open to a closed conformational state upon ligand binding. Members of this group are predicted to be involved in the transport of sugar-containing molecules across cellular and organellar membranes; however their substrate specificity is not known in detail.

periplasmic glucose/galactose-binding protein (GGBP) involved in chemotaxis towards, and active transport of, glucose and galactose in various bacterial species; Periplasmic glucose/galactose-binding protein (GGBP) involved in chemotaxis towards, and active transport of, glucose and galactose in various bacterial species. GGBP is a member of the pentose/hexose sugar-binding protein family of the type 1 periplasmic binding protein superfamily which consists of two alpha/beta globular domains connected by a three-stranded hinge. This Venus flytrap-like domain undergoes transition from an open to a closed conformational state upon ligand binding. Moreover, the periplasmic GGBP is homologous to the ligand-binding domain of eukaryotic receptors such as glutamate receptor (GluR) and DNA-binding transcriptional repressors such as LacI and GalR.

ligand binding domain of the LacI transcriptional regulator family belonging to the type 1 periplasmic-binding fold protein superfamily; Ligand binding domain of the LacI transcriptional regulator family belonging to the type 1 periplasmic-binding fold protein superfamily. In most cases, ligands are monosaccharide including lactose, ribose, fructose, xylose, arabinose, galactose/glucose, and other sugars. The LacI family of proteins consists of transcriptional regulators related to the lac repressor. In this case, the domain sugar binding changes the DNA binding activity of the repressor domain.

41-286 9.29e-32

monosaccharide ABC transporter substrate-binding protein; Periplasmic sugar-binding domain of active transport systems that are members of the type 1 periplasmic binding protein (PBP1) superfamily. The members of this family function as the primary receptors for chemotaxis and transport of many sugar based solutes in bacteria and archaea. The sugar binding domain is also homologous to the ligand-binding domain of eukaryotic receptors such as glutamate receptor (GluR) and DNA-binding transcriptional repressors such as LacI and GalR. Moreover, this periplasmic binding domain, also known as Venus flytrap domain, undergoes transition from an open to a closed conformational state upon the binding of ligands such as lactose, ribose, fructose, xylose, arabinose, galactose/glucose, and other sugars. This family also includes the periplasmic binding domain of autoinducer-2 (AI-2) receptors such as LsrB and LuxP which are highly homologous to periplasmic pentose/hexose sugar-binding proteins.

41-305 6.27e-31

ligand binding domain of the lacI-like transcription regulator from a novel metal-reducing bacterium Alkaliphilus Metalliredigens (strain Qymf) and its close homologs; This group includes the ligand binding domain of the lacI-like transcription regulator from a novel metal-reducing bacterium Alkaliphilus metalliredigens (strain Qymf) and its close homologs. Qymf is a strict anaerobe that could be grown in the presence of borax and its cells are straight rods that produce endospores. This group is a member of the LacI-GalR family repressors that are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the sugar-binding domain of ABC-type transport systems that contain the type 1 periplasmic binding protein-like fold. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding affinity of the repressor.

TorT-like proteins, a periplasmic binding protein family that activates induction of the Tor respiratory system upon trimethylamine N-oxide (TMAO) electron-acceptor binding in bacteria; TorT-like proteins, a periplasmic binding protein family that activates induction of the Tor respiratory system upon trimethylamine N-oxide (TMAO) electron-acceptor binding in bacteria. The Tor respiratory system is consists of three proteins (TorC, TorA, and TorD) and is induced in the presence of TMAO. The TMAO control is tightly regulated by three proteins: TorS, TorT, and TorR. Thus, the disruption of any of these proteins can abolish the Tor respiratory induction. TorT shares homology with the sugar-binding domain of the type 1 periplasmic binding proteins. The members of TorT-like family bind TMAO or related compounds and are predicted to be involved in signal transduction and/or substrate transport.

Ligand-binding domain of the LacI-GalR family of transcription regulators and the sugar-binding domain of ABC-type transport systems; Ligand-binding domain of the LacI-GalR family of transcription regulators and the sugar-binding domain of ABC-type transport systems, all of which contain the type 1 periplasmic binding protein-like fold. Their specific ligands include lactose, ribose, fructose, xylose, arabinose, galactose/glucose, and other sugars. The LacI family of proteins consists of transcriptional regulators related to the lac repressor; in general the sugar binding domain in this family binds a sugar, which in turn changes the DNA binding activity of the repressor domain. The core structure of the periplasmic binding proteins is classified into two types and they differ in number and order of beta strands in each domain: type 1, which has six beta strands, and type 2, which has five beta strands. These two distinct structural arrangements may have originated from a common ancestor.

41-304 6.81e-28

ligand-binding domain of uncharacterized DNA-binding regulatory proteins that are members of the LacI-GalR family of bacterial transcription repressors; This group includes the ligand-binding domain of uncharacterized DNA-binding regulatory proteins that are members of the LacI-GalR family of bacterial transcription repressors. The LacI-GalR family repressors are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the sugar-binding domain of ABC-type transport systems that contain the type 1 periplasmic binding protein-like fold. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding affinity of the repressor.

ligand-binding domain of MalI, a transcription regulator of the maltose system of Escherichia coli and its close homologs from other bacteria; This group includes the ligand-binding domain of MalI, a transcription regulator of the maltose system of Escherichia coli and its close homologs from other bacteria. They are members of the LacI-GalR family of repressor proteins which are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the sugar-binding domain of ABC-type transport systems that contain the type 1 periplasmic binding protein-like fold. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding affinity of the repressor.

41-307 8.18e-25

ligand binding domain of DNA transcription iso-repressor GalS, which is one of two regulatory proteins involved in galactose transport and metabolism; Ligand binding domain of DNA transcription iso-repressor GalS, which is one of two regulatory proteins involved in galactose transport and metabolism. Transcription of the galactose regulon genes is regulated by Gal iso-repressor (GalS) and Gal repressor (GalR) in different ways, but both repressors recognize the same DNA binding site in the absence of D-galactose. GalS is a dimeric protein like GalR,and its major role is in regulating expression of the high-affinity galactose transporter encoded by the mgl operon, whereas GalR is the exclusive regulator of galactose permease, the low-affinity galactose transporter. GalS and GalR are members of the LacI-GalR family of transcription regulators and both contain the type 1 periplasmic binding protein-like fold. Hence, they are homologous to the periplasmic sugar binding of ABC-type transport systems.

45-304 1.03e-22

ligand-binding domain of an uncharacterized transcription regulator from Actinobacillus succinogenes and its close homologs from other bacteria; This group includes the ligand-binding domain of an uncharacterized transcription regulator from Actinobacillus succinogenes and its close homologs from other bacteria. This group belongs to the LacI-GalR family repressors and are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the sugar-binding domain of ABC-type transport systems that contain the type 1 periplasmic binding protein-like fold. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding.

monosaccharide ABC transporter substrate binding protein such as CUT2; Periplasmic sugar-binding component of uncharacterized ABC-type transport systems that are members of the pentose/hexose sugar-binding protein family of the type 1 periplasmic binding protein superfamily, which consists of two alpha/beta globular domains connected by a three-stranded hinge. This Venus flytrap-like domain undergoes transition from an open to a closed conformational state upon ligand binding. Members of this group are predicted to be involved in the transport of sugar-containing molecules across cellular and organellar membranes; however their substrate specificity is not known in detail.

Type 1 periplasmic binding fold superfamily; Type 1 periplasmic binding fold superfamily. This model and hierarchy represent the ligand binding domains of the LacI family of transcriptional regulators, periplasmic binding proteins of the ABC-type transport systems, the family C G-protein couples receptors (GPCRs), membrane bound guanylyl cyclases including the family of natriuretic peptide receptors (NPRs), and the N-terminal leucine-isoleucine-valine binding protein (LIVBP)-like domains of the ionotropic glutamate receptors (iGluRs). In LacI-like transcriptional regulator and the bacterial periplasmic binding proteins, the ligands are monosaccharides, including lactose, ribose, fructose, xylose, arabinose, galactose/glucose and other sugars, with a few exceptions. Periplasmic sugar binding proteins are one of the components of ABC transporters and are involved in the active transport of water-soluble ligands. The LacI family of proteins consists of transcriptional regulators related to the lac repressor. In this case, the sugar binding domain binds a sugar which changes the DNA binding activity of the repressor domain. The periplasmic binding proteins are the primary receptors for chemotaxis and transport of many sugar based solutes. The core structures of periplasmic binding proteins are classified into two types, and they differ in number and order of beta strands: type 1 has six beta strands while type 2 has five beta strands per sub-domain. These two structural folds are thought to be distantly related via a common ancestor. Notably, while the N-terminal LIVBP-like domain of iGluRs belongs to the type 1 periplasmic-binding fold protein superfamily, the glutamate-binding domain of the iGluR is structurally similar to the type 2 periplasmic-binding fold.

ligand-binding domain of putative DNA transcription regulators highly similar to that of the catabolite control protein A (CcpA), which functions as the major transcriptional regulator of carbon catabolite repression/regulation; This group includes the ligand-binding domain of uncharacterized DNA transcription repressors highly similar to that of the catabolite control protein A (CcpA), which functions as the major transcriptional regulator of carbon catabolite repression/regulation (CCR), a process in which enzymes necessary for the metabolism of alternative sugars are inhibited in the presence of glucose. In gram-positive bacteria, CCR is controlled by HPr, a phosphoenolpyruvate:sugar phsophotrasnferase system (PTS) and a transcriptional regulator CcpA. Moreover, CcpA can regulate sporulation and antibiotic resistance as well as play a role in virulence development of certain pathogens such as the group A streptococcus. The ligand binding domain of CcpA is a member of the LacI-GalR family of bacterial transcription regulators.

40-291 1.86e-17

periplasmic binding domain of autoinducer-2 (AI-2) receptor LsrB from Salmonella typhimurium and its close homologs; Periplasmic binding domain of autoinducer-2 (AI-2) receptor LsrB from Salmonella typhimurium and its close homologs from other bacteria. The members of this group are homologous to a family of periplasmic pentose/hexose sugar-binding proteins that function as the primary receptors for chemotaxis and transporters of many sugar based solutes in bacteria and archaea and that are a member of the type 1 periplasmic binding protein superfamily. LsrB, which is part of the ABC transporter complex LsrABCD, binds a chemically distinct form of the AI-2 signal that lacks boron, in contrast to the Vibrio harveyi AI-2 signaling molecule that has an unusual furanosyl borate diester. Hence, many bacteria coordinate their gene expression according to the local density of their population by producing species specific AI-2. This process of quorum sensing allows LsrB to function as a periplasmic AI-2 binding protein in interspecies signaling.

41-307 2.19e-17

ligand-binding domain of DNA-binding regulatory protein from Corynebacterium glutamicum produces significant amounts of L-glutamate directly from cheap sugar and ammonia; This group includes the ligand-binding domain of DNA-binding regulatory protein from Corynebacterium glutamicum which has a unique ability to produce significant amounts of L-glutamate directly from cheap sugar and ammonia. This regulatory protein is a member of the LacI-GalR family of bacterial transcription repressors. The LacI-GalR family repressors are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the sugar-binding domain of ABC-type transport systems that contain the type 1 periplasmic binding protein-like fold. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding affinity of the repressor.

59-304 1.09e-16

ligand-binding domain of DNA transcription repressor LacI specific for lactose, a member of the LacI-GalR family of bacterial transcription regulators; Ligand-binding domain of DNA transcription repressor LacI specific for lactose, a member of the LacI-GalR family of bacterial transcription regulators. The ligand-binding domain of LacI is structurally homologous to the periplasmic sugar-binding domain of ABC-type transporters and both domains contain the type 1 periplasmic binding protein-like fold. The LacI-GalR family repressors are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the type 1 periplasmic binding proteins. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding affinity of the repressor.

38-306 4.92e-16

Periplasmic binding proteins and sugar binding domain of LacI family; This family includes the periplasmic binding proteins, and the LacI family transcriptional regulators. The periplasmic binding proteins are the primary receptors for chemotaxis and transport of many sugar based solutes. The LacI family of proteins consist of transcriptional regulators related to the lac repressor. In this case, generally the sugar binding domain binds a sugar which changes the DNA binding activity of the repressor domain (pfam00356).

ligand-binding domain of DNA-binding regulatory proteins specific to sucrose that are members of the LacI-GalR family of bacterial transcription repressors; This group includes the ligand-binding domain of DNA-binding regulatory proteins specific to sucrose that are members of the LacI-GalR family of bacterial transcription repressors. The LacI-GalR family repressors are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the sugar-binding domain of ABC-type transport systems that contain the type 1 periplasmic binding protein-like fold. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding affinity of the repressor.

50-292 2.24e-14

ligand-binding protein LsrB of ABC transporter periplasmic binding protein; Periplasmic binding domain of autoinducer-2 (AI-2) receptor LsrB from Salmonella typhimurium and its close homologs from other bacteria. The members of this group are homologous to a family of periplasmic pentose/hexose sugar-binding proteins that function as the primary receptors for chemotaxis and transporters of many sugar based solutes in bacteria and archaea and that are a member of the type 1 periplasmic binding protein superfamily. LsrB, which is part of the ABC transporter complex LsrABCD, binds a chemically distinct form of the AI-2 signal that lacks boron, in contrast to the Vibrio harveyi AI-2 signaling molecule that has an unusual furanosyl borate diester. Hence, many bacteria coordinate their gene expression according to the local density of their population by producing species specific AI-2. This process of quorum sensing allows LsrB to function as a periplasmic AI-2 binding protein in interspecies signaling.

periplasmic binding protein (LuxP) of autoinducer-2 (AI-2) receptor LuxPQ from Vibrio harveyi and its close homologs; Periplasmic binding protein (LuxP) of autoinducer-2 (AI-2) receptor LuxPQ from Vibrio harveyi and its close homologs from other bacteria. The members of this group are highly homologous to a family of periplasmic pentose/hexose sugar-binding proteins that function as the primary receptors for chemotaxis and transport of many sugar based solutes in bacteria and archaea, and that are members of the type 1 periplasmic binding protein superfamily. The Vibrio harveyi AI-2 receptor consists of two polypeptides, LuxP and LuxQ: LuxP is a periplasmic binding protein that binds AI-2 by clamping it between two domains, LuxQ is an integral membrane protein belonging to the two-component sensor kinase family. Unlike AI-2 bound to the LsrB receptor in Salmonella typhimurium, the Vibrio harveyi AI-2 signaling molecule has an unusual furanosyl borate diester. Hence, many bacteria coordinate their gene expression according to the local density of their population by producing species specific AI-2. This process of quorum sensing allows LuxPQ to control light production as well as its motility behavior.

Ligand-binding domain of uncharacterized DNA transcription repressors highly similar to that of the repressors specific raffinose (RafR) and alpha-glucosides (AglR) which are members of the LacI-GalR family of bacterial transcription regulators; This group includes the ligand-binding domain of uncharacterized DNA-binding regulatory proteins highly similar to DNA transcription repressors specific for raffinose (RafR) and alpha-glucosides (AglR). Members of this group belong to the LacI-GalR family of bacterial transcription repressors. The LacI-GalR family repressors are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the sugar-binding domain of ABC-type transport systems that contain the type I periplasmic binding protein-like fold. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding affinity of the repressor.

121-306 1.59e-11

ligand-binding domain of TTHA0807, a CcpA regulator, from Thermus thermophilus HB8 and its close homologs; Ligand-binding domain of the uncharacterized transcription regulator TTHA0807 from the extremely thermophilic organism Thermus thermophilus HB8 and close homologs from other bacteria. Although its exact biological function is not known, the TTHA0807 belongs to the catabolite control protein A (CcpA)family of regulatory proteins. The CcpA functions as the major transcriptional regulator of carbon catabolite repression/regulation (CCR), a process in which enzymes necessary for the metabolism of alternative sugars are inhibited in the presence of glucose. In gram-positive bacteria, CCR is controlled by HPr, a phosphoenolpyruvate:sugar phsophotrasnferase system (PTS) and a transcriptional regulator CcpA. Moreover, CcpA can regulate sporulation and antibiotic resistance as well as play a role in virulence development of certain pathogens such as the group A streptococcus. The ligand binding domain of CcpA is a member of the LacI-GalR family of bacterial transcription regulators.

48-305 1.63e-11

ligand-binding domain of DNA transcription repressor GalR which is one of two regulatory proteins involved in galactose transport and metabolism; Ligand-binding domain of DNA transcription repressor GalR which is one of two regulatory proteins involved in galactose transport and metabolism. Transcription of the galactose regulon genes is regulated by Gal iso-repressor (GalS) and Gal repressor (GalR) in different ways, but both repressors recognize the same DNA binding site in the absence of D-galactose. GalR is a dimeric protein like GalS and is exclusively involved in the regulation of galactose permease, the low-affinity galactose transporter. GalS is involved in regulating expression of the high-affinity galactose transporter encoded by the mgl operon. GalS and GalR are members of the LacI-GalR family of transcription regulators and both contain the type 1 periplasmic binding protein-like fold. Hence, they are structurally homologous to the periplasmic sugar binding of ABC-type transport systems.

40-291 2.04e-10

rhamnose ABC transporter substrate-binding protein; Rhamnose ABC transporter substrate-binding protein similar to periplasmic binding domain of autoinducer-2 (AI-2) receptor LsrB from Salmonella typhimurium. The members of this group are homologous to a family of periplasmic pentose/hexose sugar-binding proteins that function as the primary receptors for chemotaxis and transporters of many sugar based solutes in bacteria and archaea and that are a member of the type 1 periplasmic binding protein superfamily. LsrB, which is part of the ABC transporter complex LsrABCD, binds a chemically distinct form of the AI-2 signal that lacks boron, in contrast to the Vibrio harveyi AI-2 signaling molecule that has an unusual furanosyl borate diester. Hence, many bacteria coordinate their gene expression according to the local density of their population by producing species specific AI-2. This process of quorum sensing allows LsrB to function as a periplasmic AI-2 binding protein in interspecies signaling.

Periplasmic binding protein-like domain; This domain is found in a variety of transcriptional regulatory proteins. It is related to bacterial periplasmic binding proteins, although this domain is unlikely to be found in the periplasm. This domain acts as a sensor binding small molecule ligands that the DNA-binding domain responds to. This domain recognizes Sugars, sugar phosphates, sugar acids and purines (Matilla et. al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).

41-306 2.41e-10

ligand-binding domain of a novel transcription factor implicated in catabolite repression in Bacillus and Clostridium species; This group includes the ligand-binding domain of a novel transcription factor implicated in catabolite repression in Bacillus and Clostridium species. Catabolite control protein B (CcpB) is 30% identical in sequence to CcpA which functions as the major transcriptional regulator of carbon catabolite repression/regulation (CCR), a process in which enzymes necessary for the metabolism of alternative sugars are inhibited in the presence of glucose. Like CcpA, the DNA-binding protein CcpB exerts its catabolite-repressing effect by a mechanism dependent on the presence of HPr(Ser-P), the small phosphocarrier proteins of the phosphoenolpyruvate-sugar phosphotransferase system, but with a less significant degree.

49-304 6.88e-10

ligand-binding domain of DNA transcription repressor SalR, a member of the LacI-GalR family of bacterial transcription regulators; Ligand-binding domain of DNA transcription repressor SalR, a member of the LacI-GalR family of bacterial transcription regulators. The SalR binds to glucose based compound Salicin which is chemically related to aspirin. The ligand-binding of SalR is structurally homologous to the periplasmic sugar-binding domain of ABC-transporters and both domains contain the type 1 periplasmic binding protein-like fold. The LacI-GalR family repressors are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the type 1 periplasmic binding proteins. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding affinity of the repressor.

51-292 3.65e-08

ligand-binding protein LsrB-like of ABC transporter periplasmic binding protein; Ligand-binding protein LsrB-like of a transport system, similar to periplasmic binding domain of autoinducer-2 (AI-2) receptor LsrB from Salmonella typhimurium and its close homologs from other bacteria. The members of this group are homologous to a family of periplasmic pentose/hexose sugar-binding proteins that function as the primary receptors for chemotaxis and transporters of many sugar based solutes in bacteria and archaea and that are a member of the type 1 periplasmic binding protein superfamily. LsrB, which is part of the ABC transporter complex LsrABCD, binds a chemically distinct form of the AI-2 signal that lacks boron, in contrast to the Vibrio harveyi AI-2 signaling molecule that has an unusual furanosyl borate diester. Hence, many bacteria coordinate their gene expression according to the local density of their population by producing species specific AI-2. This process of quorum sensing allows LsrB to function as a periplasmic AI-2 binding protein in interspecies signaling.

41-304 4.22e-08

ligand-binding domain of uncharacterized DNA-binding regulatory proteins that are members of the LacI-GalR family of bacterial transcription repressors; This group includes the ligand-binding domain of uncharacterized DNA-binding regulatory proteins that are members of the LacI-GalR family of bacterial transcription repressors. The LacI-GalR family repressors are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the sugar-binding domain of ABC-type transport systems that contain the type 1 periplasmic binding protein-like fold. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding affinity of the repressor.

45-293 5.13e-07

ligand-binding protein LsrB-like of ABC transporter periplasmic binding protein; Ligand-binding protein LsrB-like of a transport system, similar to periplasmic binding domain of autoinducer-2 (AI-2) receptor LsrB from Salmonella typhimurium and its close homologs from other bacteria. The members of this group are homologous to a family of periplasmic pentose/hexose sugar-binding proteins that function as the primary receptors for chemotaxis and transporters of many sugar based solutes in bacteria and archaea and that are a member of the type 1 periplasmic binding protein superfamily. LsrB, which is part of the ABC transporter complex LsrABCD, binds a chemically distinct form of the AI-2 signal that lacks boron, in contrast to the Vibrio harveyi AI-2 signaling molecule that has an unusual furanosyl borate diester. Hence, many bacteria coordinate their gene expression according to the local density of their population by producing species specific AI-2. This process of quorum sensing allows LsrB to function as a periplasmic AI-2 binding protein in interspecies signaling.

196-251 3.38e-05

Ligand-binding domain of DNA transcription repressor specific for alpha-glucosides (AglR) and similar proteins; Ligand-binding domain of DNA transcription repressor specific for alpha-glucosides (AglR) which is a member of the LacI-GalR family of bacterial transcription regulators. The LacI-GalR family repressors are composed of two functional domains: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the sugar-binding domain of ABC-type transport systems that contain the type I periplasmic binding protein-like fold. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcription repressor undergoes a conformational change upon ligand binding which in turn changes the DNA binding affinity of the repressor.

41-253 4.21e-04

ligand-binding domain of the catabolite control protein A (CcpA), which functions as the major transcriptional regulator of carbon catabolite repression/regulation; Ligand-binding domain of the catabolite control protein A (CcpA), which functions as the major transcriptional regulator of carbon catabolite repression/regulation (CCR), a process in which enzymes necessary for the metabolism of alternative sugars are inhibited in the presence of glucose. In gram-positive bacteria, CCR is controlled by HPr, a phosphoenolpyruvate:sugar phsophotrasnferase system (PTS) and a transcriptional regulator CcpA. Moreover, CcpA can regulate sporulation and antibiotic resistance as well as play a role in virulence development of certain pathogens such as the group A streptococcus. The ligand binding domain of CcpA is a member of the LacI-GalR family of bacterial transcription regulators.
