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. : Pssm-ID: 380483 [Multi-domain] Cd Length: 274 Bit Score: 324.51 E-value: 7.48e-111

Winged helix-turn-helix (WHTH) DNA-binding domain of the GntR family of transcriptional regulators; This CD represents the winged HTH DNA-binding domain of the GntR (named after the gluconate operon repressor in Bacillus subtilis) family of bacterial transcriptional regulators and their putative homologs found in eukaryota and archaea. The GntR family has over 6000 members distributed among almost all bacterial species, which is comprised of FadR, HutC, MocR, YtrA, AraR, PlmA, and other subfamilies for the regulation of the most varied biological process. The monomeric proteins of the GntR family are characterized by two function domains: a small highly conserved winged helix-turn-helix prokaryotic DNA binding domain in the N-terminus, and a very diverse regulatory ligand-binding domain in the C-terminus for effector-binding/oligomerization, which provides the basis for the subfamily classifications. Binding of the effector to GntR-like transcriptional regulators is presumed to result in a conformational change that regulates the DNA-binding affinity of the repressor. The GntR-like proteins bind as dimers, where each monomer recognizes a half-site of 2-fold symmetric DNA sequences. Pssm-ID: 153418 [Multi-domain] Cd Length: 66 Bit Score: 75.95 E-value: 1.60e-17

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.

In this case, generally the sugar binding domain binds a sugar which changes the DNA binding activity of the repressor domain (pfam00356).

Winged helix-turn-helix (WHTH) DNA-binding domain of the GntR family of transcriptional regulators; This CD represents the winged HTH DNA-binding domain of the GntR (named after the gluconate operon repressor in Bacillus subtilis) family of bacterial transcriptional regulators and their putative homologs found in eukaryota and archaea. The GntR family has over 6000 members distributed among almost all bacterial species, which is comprised of FadR, HutC, MocR, YtrA, AraR, PlmA, and other subfamilies for the regulation of the most varied biological process. The monomeric proteins of the GntR family are characterized by two function domains: a small highly conserved winged helix-turn-helix prokaryotic DNA binding domain in the N-terminus, and a very diverse regulatory ligand-binding domain in the C-terminus for effector-binding/oligomerization, which provides the basis for the subfamily classifications. Binding of the effector to GntR-like transcriptional regulators is presumed to result in a conformational change that regulates the DNA-binding affinity of the repressor. The GntR-like proteins bind as dimers, where each monomer recognizes a half-site of 2-fold symmetric DNA sequences. Pssm-ID: 153418 [Multi-domain] Cd Length: 66 Bit Score: 75.95 E-value: 1.60e-17

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.

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.

monosaccharide ABC transporter substrate-binding protein; Periplasmic sugar-binding domain of uncharacterized ABC-type transport systems that share homology with a family of pentose/hexose sugar-binding proteins of the type 1 periplasmic binding protein superfamily, which consists of two domains connected by a three-stranded hinge. The substrate specificity of this group is not known, but it is predicted to be involved in the transport of sugar-containing molecules and chemotaxis.

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.
