61-327 8.84e-121

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.

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).

61-327 8.84e-121

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.

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.

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 putative DNA transcription regulators highly similar to that of the transcription regulator DegA; This group includes the ligand-binding domain of uncharacterized DNA transcription repressors highly similar to that of the transcription regulator DegA, which is involved in the control of degradation of Bacillus subtilis amidophosphoribosyltransferase (purF). 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.

ligand-binding domain of purine repressor, PurR, which functions as the master regulatory protein of de novo purine nucleotide biosynthesis in Escherichia coli; Ligand-binding domain of purine repressor, PurR, which functions as the master regulatory protein of de novo purine nucleotide biosynthesis in Escherichia coli. This dimeric PurR belongs to the LacI-GalR family of transcription regulators and is activated to bind to DNA operator sites by initially binding either of high affinity corepressors, hypoxanthine or guanine. PurR is composed of two functional domains: aan 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.

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.

61-295 9.21e-53

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.

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.

61-296 2.91e-47

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.

61-295 3.65e-39

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.

61-296 1.16e-38

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.

61-298 7.98e-34

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.

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).

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.

61-292 1.38e-28

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.

62-291 4.31e-26

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.

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 transcription repressor specific for fructose (FruR) and its close homologs; Ligand binding domain of DNA transcription repressor specific for fructose (FruR) and its close homologs, all of which are members 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 members of the type 1 periplasmic binding protein superfamily. 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

Helix-turn-helix (HTH) DNA binding domain of the LacI family of transcriptional regulators; ...
5-56 1.03e-19

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.

61-328 1.15e-17

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.

61-273 1.09e-15

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.

142-291 7.70e-10

ligand-binding domain of DNA transcription repressor specific for xylose (XylR); Ligand-binding domain of DNA transcription repressor specific for xylose (XylR), a member of the LacI-GalR family of bacterial transcription regulators. The ligand-binding domain of XylR 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.

156-288 3.21e-06

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.

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 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.

periplasmic L-arabinose-binding protein (ABP), a member of a family of pentose/hexose sugar-binding proteins of the type 1 periplasmic binding protein superfamily; Periplasmic L-arabinose-binding protein (ABP), a member of a family of pentose/hexose sugar-binding proteins of the type 1 periplasmic binding protein superfamily. ABP is only involved in transport contrary to other related sugar-binding proteins such as the glucose/galactose-binding protein (GGBP) and the ribose-binding protein (RBP), both of which are involved in chemotaxis as well as transport. The periplasmic ABP consists of two alpha/beta globular domains connected by a three-stranded hinge, a Venus flytrap-like domain, which undergoes a transition from an open to a closed conformational state upon ligand binding. Moreover, ABP is homologous to the ligand-binding domain of eukaryotic receptors such as metabotropic glutamate receptor (mGluR) and DNA-binding transcriptional repressors such as LacI and GalR.
