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).

64-332 5.94e-54

ligand-binding domain of DNA transcription repressor RegR and other putative regulators such as KdgR and EndR; Ligand-binding domain of DNA transcription repressor RegR and other putative regulators such as KdgR and EndR, all of which are members of the LacI-GalR family of bacterial transcription regulators. RegR regulates bacterial competence and the expression of virulence factors, including hyaluronidase. 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.

63-334 2.87e-34

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 DNA transcription repressor GntR specific for gluconate, a member of the LacI-GalR family of bacterial transcription regulators; This group represents the ligand-binding domain of DNA transcription repressor GntR specific for gluconate, a member of the LacI-GalR family of bacterial transcription regulators. The ligand-binding domain of GntR 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.

63-334 4.53e-31

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.

ligand-binding domain of DNA transcription repressor specific for arabinose (AraR) which is a member of the LacI-GalR family of bacterial transcription regulators; Ligand-binding domain of DNA transcription repressor specific for arabinose (AraR) which is a member of the LacI-GalR family of bacterial transcription regulators. The ligand-binding domain of AraR 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.

63-333 3.02e-28

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.

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.

ligand-binding domain of a LacI-like transcriptional regulator, CatR which is involved in catechol degradation; This group includes the ligand-binding domain of a LacI-like transcriptional regulator, CatR which is involved in catechol degradation. This group belongs to 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.

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).

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.

ligand-binding domain of an uncharacterized transcription regulator from Corynebacterium glutamicum and its close homologs from other bacteria; This group includes the ligand-binding domain of an uncharacterized transcription regulator from Corynebacterium glutamicum 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.

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).

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.

7-58 2.41e-17

Helix-turn-helix (HTH) DNA binding domain of the LacI family of transcriptional regulators; HTH-DNA binding domain of the LacI (lactose operon repressor) family of bacterial transcriptional regulators and their putative homologs found in plants. The LacI family has more than 500 members distributed among almost all bacterial species. The monomeric proteins of the LacI family contain common structural features that include a small DNA-binding domain with a helix-turn-helix motif in the N-terminus, a regulatory ligand-binding domain which exhibits the type I periplasmic binding protein fold in the C-terminus for oligomerization and for effector binding, and an approximately 18-amino acid linker connecting these two functional domains. In LacI-like transcriptional regulators, the ligands are monosaccharides including lactose, ribose, fructose, xylose, arabinose, galactose/glucose, and other sugars, with a few exceptions. When the C-terminal domain of the LacI family repressor binds its ligand, it undergoes a conformational change which affects the DNA-binding affinity of the repressor. In Escherichia coli, LacI represses transcription by binding with high affinity to the lac operon at a specific operator DNA sequence until it interacts with the physiological inducer allolactose or a non-degradable analog IPTG (isopropyl-beta-D-thiogalactopyranoside). Induction of the repressor lowers its affinity for the operator sequence, thereby allowing transcription of the lac operon structural genes (lacZ, lacY, and LacA). The lac repressor occurs as a tetramer made up of two functional dimers. Thus, two DNA binding domains of a dimer are required to bind the inverted repeat sequences of the operator DNA binding sites.

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.

64-332 9.83e-15

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.

63-329 2.27e-14

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.

63-330 4.04e-14

Ligand-binding domain of DNA transcription repressor specific for raffinose (RafR) and similar proteins; Ligand-binding domain of DNA transcription repressor specific for raffinose (RafR) 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.

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.

139-334 1.41e-07

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.
