Protein Domain |
Type: |
Domain |
Description: |
The nodulation (nod) genes in soil bacteria play important roles in the development of nodules. nod genes are involved in synthesis of Nod factors that are required for bacterial entry into root hairs. Thirteen nod genes have been identified and are classified into five transcription units: nodD, nodABCIJ, nodFEL, nodMNT, and nodO. NodD negatively auto-regulates expression of nodD gene, while other nod genes are inducible and positively regulated by NodD in the presence of flavonoids released by plant roots [, , ]. This substrate-binding domain has significant homology to the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine. The PBP2 bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. After binding their specific ligand with high affinity, they can interact with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis. Besides transport proteins, the PBP2 superfamily includes the substrate- binding domains from ionotropic glutamate receptors, LysR-like transcriptional regulators, and unorthodox sensor proteins involved in signal transduction [, , ]. |

Type: |
Domain |
Description: |
This entry represents the C-terminal substrate binding domain of LysR-type transcriptional regulator AmpR, whichis involved in control of the expression of beta-lactamase genes []. Beta-lactamases are responsible for bacterial resistance to beta-lactam antibiotics such as penicillins. AmpR regulates the expression of beta-lactamases in many enterobacterial strains and many other Gram-negative bacilli. AmpR is a key player in the intricate network of regulators that is responsible for mediating virulence and antibiotic resistance in P. aeruginosa []. The topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine. The PBP2 bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. After binding their specific ligand with high affinity, they can interact with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.

Description: |
This entry represents the C-terminal substrate-domain of LysR-type transcriptional regulator NocR, which is involved in the catabolism of opines. Opines, such as octopine and nopaline, are low molecular weight compounds found in plant crown gall tumours that are produced by the parasitic bacterium Agrobacterium. There are at least 30 different opines identified so far. Opines are utilized by tumor-colonizing bacteria as a source of carbon, nitrogen, and energy. NocR positively regulates the catabolism of nopaline. Both nopaline and octopalin are arginine derivatives. In Agrobacterium tumefaciens, NocR regulates expression of the divergently transcribed nocB and nocR genes of the nopaline catabolism (noc) region [, ]. This substrate-binding domain shows significant homology to the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine. The PBP2 bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

Description: |
Galactose-binding protein regulator (GbpR), a member of the LysR family of bacterial transcriptional regulators, regulates the expression of chromosomal virulence gene chvE []. The chvE gene is involved in the uptake of specific sugars, in chemotaxis to these sugars, and in the VirA-VirG two-component signal transduction system. In the presence of an inducing sugar such as L-arabinose, D-fucose, or D-galactose, GbpR activates chvE expression, while in the absence of an inducing sugar, GbpR represses expression []. The topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine. The PBP2 bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. After binding their specific ligand with high affinity, they can interact with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis. Besides transport proteins, the PBP2 superfamily includes the substrate- binding domains from ionotropic glutamate receptors, LysR-like transcriptional regulators, and unorthodox sensor proteins involved in signal transduction [, , ]. |

In Escherichia coli, XapR is a positive regulator for the expression of xapA gene, encoding xanthosine phosphorylase, and xapB gene, encoding a polypeptide similar to the nucleotide transport protein NupG. As an operon, the expression of both xapA and xapB is fully dependent on the presence of both XapR and the inducer xanthosine. Expression of the xapR is constitutive but not auto-regulated, unlike many other LysR family proteins []. This substrate-binding domain shows significant homology to the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine. The PBP2 bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

Description: |
This entry represents the substrate binding domain of BudR regulator, which is responsible for induction of the butanediol formation pathway under fermentative growth conditions. Three enzymes are involved in the production of 1 mol of 2,3 butanediol from the condensation of 2 mol of pyruvate with acetolactate and acetoin as intermediates: acetolactate synthetase, acetolactate decarboxylase, and acetoin reductase. In Klebsiella terrigena, BudR regulates the expression of the budABC operon genes, encoding these three enzymes of the butanediol pathway []. In many bacterial species, the use of this pathway can prevent intracellular acidification by diverting metabolism from acid production to the formation of neutral compounds (acetoin and butanediol). This substrate-binding domain has significant homology to the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine.

Description: |
AlsR is responsible for activating the expression of the acetoin operon (alsSD) in response to inducing signals such as glucose and acetate. Like many other LysR family proteins, AlsR is transcribed divergently from the alsSD operon []. The alsS gene encodes acetolactate synthase, an enzyme involved in the production of acetoin in cells of stationary-phase. AlsS catalyzes the conversion of two pyruvate molecules to acetolactate and carbon dioxide. Acetolactate is then converted to acetoin at low pH by acetolactate decarboxylase which encoded by the alsD gene. Acetoin is an important physiological metabolite excreted by many microorganisms grown on glucose or other fermentable carbon sources []. This substrate-binding domain shows significant homology to the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine.

Description: |
Rhizobium is a nitrogen fixing bacteria present in the roots of leguminous plants, which fixes atmospheric nitrogen to the soil. Most Rhizobium species possess multiple nodulation (nod) genes for the development of nodules. For example, Rhizobium meliloti possesses three copies of nodD genes. NodD1 and NodD2 activate nod operons when Rhizobium is exposed to inducers synthesized by the host plant, while NodD3 acts independent of plant inducers and requires the symbiotic regulator SyrM for nod gene expression. SyrM activates the expression of the regulatory nodulation gene nodD3. In turn, NodD3 activates expression of syrM. In addition, SyrM is involved in exopolysaccharide synthesis []. This substrate-binding domain shows significant homology to the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine.

In soil bacterium Pseudomonas putida, the ortho-pathways of catechol and 3-chlorocatechol are central catabolic pathways that convert aromatic and chloroaromaric compounds to tricarboxylic acid (TCA) cycle intermediates. The 3-chlorocatechol-degradative pathway is encoded by clcABD operon, which requires the divergently transcribed clcR and an intermediate of the pathway, 2-chloromuconate, as an inducer for activation []. The topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine.

This entry represents the C-terminal substrate binding domain of LysR-type transcriptional regulator BlaA, which is involved in control of the expression of beta-lactamase genes, blaA and blaB. Beta-lactamases are responsible for bacterial resistance to beta-lactam antibiotics such as penicillins. The blaA gene is located just upstream of blaB in the opposite direction and regulates the expression of the blaB. BlaA also negatively auto-regulates the expression of its own gene, blaA. BlaA (a constitutive class A penicllinase) belongs to the LysR family of transcriptional regulators, whereas BlaB (an inducible class C cephalosporinase or AmpC) can be referred to as a penicillin binding protein but it does not act as a beta-lactamase []. The topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine.

CynR is a LysR-like transcriptional regulator of the cyn operon, which encodes genes that allow cyanate to be used as a sole source of nitrogen. The operon includes three genes in the following order: cynT (cyanate permease), cynS (cyanase), and cynX (a protein of unknown function) []. CynR negatively regulates its own expression independently of cyanate. CynR binds to DNA and induces bending of DNA in the presence or absence of cyanate, but the amount of bending is decreased by cyanate. CynR, as other LysR-type transcriptional regulators, is composed of two functional domains joined by a linker helix involved in oligomerization: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal substrate-binding domain, which is structurally homologous to the type 2 periplasmic binding proteins (PBP2) [].

In Escherichia coli, IlvY is required for the regulation of ilvC gene expression that encodes acetohydroxy acid isomeroreductase (AHIR), a key enzyme in the biosynthesis of branched-chain amino acids (isoleucine, valine, and leucine). The ilvGMEDA operon genes encode remaining enzyme activities required for the biosynthesis of these amino acids []. Activation of ilvC transcription by IlvY requires the additional binding of a co-inducer molecule (either alpha-acetolactate or alpha-acetohydoxybutyrate, the substrates for AHIR) to a preformed complex of IlvY protein-DNA []. Like many other LysR-family members, IlvY negatively auto-regulates the transcription of its own divergently transcribed ilvY gene in an inducer-independent manner []. This substrate-binding domain has significant homology to the type 2 periplasmic binding proteins (PBP2). The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine.

Description: |
MetR, a member of the LysR family, is a positive regulator for the metA, metE, metF, and metH genes []. The sulfur-containing amino acid methionine is the universal initiator of protein synthesis in all known organisms and its derivative S-adenosylmethionine (SAM) and autoinducer-2 (AI-2) are involved in various cellular processes. SAM plays a central role as methyl donor in methylation reactions, which are essential for the biosynthesis of phospholipids, proteins, DNA and RNA. The interspecies signaling molecule AI-2 is involved in cell-cell communication process (quorum sensing) and gene regulation in bacteria. Although methionine biosynthetic enzymes and metabolic pathways are well conserved in bacteria, the regulation of methionine biosynthesis involves various regulatory mechanisms. In Escherichia coli and Salmonella enterica serovar Typhimurium, MetJ and MetR regulate the expression of methionine biosynthetic genes []. The MetJ repressor negatively regulates the E. coli met genes, except for metH []. Several of these genes are also under the positive control of MetR with homocysteine as a co-inducer. In Bacillus subtilis, the met genes are controlled by S-box termination-antitermination system. This substrate-binding domain shows significant homology to the type 2 periplasmic binding proteins (PBP2).The PBP2 are responsible for the uptake of a variety of substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine. The PBP2 bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. After binding their specific ligand with high affinity, they can interact with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.

CysB is a transcriptional activator of genes involved in sulfate and thiosulfate transport, sulfate reduction, and cysteine synthesis. In Escherichia coli, the regulation of transcription in response to sulfur source is attributed to two transcriptional regulators, CysB and Cbl []. CysB, in association with Cbl, downregulates the expression of ssuEADCB operon which is required for the utilization of sulfur from aliphatic sulfonates, in the presence of cysteine []. Also, Cbl and CysB together directly function as transcriptional activators of tauABCD genes, which are required for utilization of taurine as sulfur source for growth []. Like many other members of the LTTR family, CysB is composed of two functional domains joined by a linker helix involved in oligomerization: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal substrate-binding domain, which is structurally homologous to the type 2 periplasmic binding proteins []. As also observed in the periplasmic binding proteins, the C-terminal domain of the bacterial transcriptional repressor undergoes a conformational change upon substrate binding which in turn changes the DNA binding affinity of the repressor [].

Cbl is a member of the LysR transcriptional regulators that comprise the largest family of prokaryotic transcription factor. Cbl shows high sequence similarity to CysB, the LysR-type transcriptional activator of genes involved in sulfate and thiosulfate transport, sulfate reduction, and cysteine synthesis []. In Escherichia coli, the function of Cbl is required for expression of sulfate starvation-inducible (ssi) genes, coupled with the biosynthesis of cysteine from the organic sulfur sources (sulfonates). The ssi genes include the ssuEADCB and tauABCD operons encoding uptake systems for organosulfur compounds, aliphatic sulfonates, and taurine []. The genes in these operons encode an ABC-type transport system required for uptake of aliphatic sulfonates and a desulfonation enzyme. Both Cbl and CysB require expression of the tau and ssu genes. Like many other members of the LTTR family, the Cbl is composed of two functional domains joined by a linker helix involved in oligomerization: an N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal substrate-binding domain, which is structurally homologous to the type 2 periplasmic binding proteins.
