99-288 8.22e-24

The C-terminal substrate binding domain of LysR-type transcriptional regulator LeuO, an activator of leucine synthesis operon, contains the type 2 periplasmic binding fold; LeuO, a LysR-type transcriptional regulator, was originally identified as an activator of the leucine synthesis operon (leuABCD). Subsequently, LeuO was found to be not a specific regulator of the leu gene but a global regulator of unrelated various genes. LeuO activates bglGFB (utilization of beta-D-glucoside) and represses cadCBA (lysine decarboxylation) and dsrA (encoding a regulatory small RNA for translational control of rpoS and hns). LeuO also regulates the yjjQ-bglJ operon which coding for a LuxR-type transcription factor. In Salmonella enterica serovar Typhi, LeuO is a positive regulator of ompS1 (encoding an outer membrane), ompS2 (encoding a pathogenicity determinant), and assT, while LeuO represses the expression of OmpX and Tpx. Both osmS1 and osmS2 influence virulence in the mouse model of Salmonella. In Vibrio cholerae, LeuO is involved in control of biofilm formation and in the stringent response. The topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2), which 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.

11-293 4.69e-16

selenium metabolism-associated LysR family transcriptional regulator; LysR family transcriptional regulators regularly appear encoded adjacent to selenecysteine incorporation proteins such as SelB. This model represents one especially well-conserved subgroup of such transcription factors from species such as Merdimonas faecis, Sellimonas intestinalis, Syntrophotalea acetylenica, and Hydrogenivirga caldilitoris. Seed alignment members were selected by proximity to selB, but not all family members are expected to have similar genomic locations.

99-288 8.22e-24

The C-terminal substrate binding domain of LysR-type transcriptional regulator LeuO, an activator of leucine synthesis operon, contains the type 2 periplasmic binding fold; LeuO, a LysR-type transcriptional regulator, was originally identified as an activator of the leucine synthesis operon (leuABCD). Subsequently, LeuO was found to be not a specific regulator of the leu gene but a global regulator of unrelated various genes. LeuO activates bglGFB (utilization of beta-D-glucoside) and represses cadCBA (lysine decarboxylation) and dsrA (encoding a regulatory small RNA for translational control of rpoS and hns). LeuO also regulates the yjjQ-bglJ operon which coding for a LuxR-type transcription factor. In Salmonella enterica serovar Typhi, LeuO is a positive regulator of ompS1 (encoding an outer membrane), ompS2 (encoding a pathogenicity determinant), and assT, while LeuO represses the expression of OmpX and Tpx. Both osmS1 and osmS2 influence virulence in the mouse model of Salmonella. In Vibrio cholerae, LeuO is involved in control of biofilm formation and in the stringent response. The topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2), which 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.

The C-terminal substrate binding domain of LysR-type transcriptional regulators that involved in the catabolism of nitroaromatic/naphthalene compounds and that of related regulators; contains the type 2 periplasmic binding fold; This CD includes the C-terminal substrate binding domain of LysR-type transcriptional regulators involved in the catabolism of dinitrotoluene and similar compounds, such as DntR, NahR, and LinR. The transcription of the genes encoding enzymes involved in such degradation is regulated and expression of these enzymes is enhanced by inducers, which are either an intermediate in the metabolic pathway or compounds to be degraded. Also included are related LysR-type regulators clustered together in phylogenetic trees, including NodD, ToxR, LeuO, SyrM, TdcA, and PnbR. This substrate-binding domain shows significant homology to the type 2 periplasmic binding proteins (PBP2), which 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.

104-296 4.93e-20

The substrate binding domain of LysR-type transcriptional regulators (LTTRs), a member of the type 2 periplasmic binding fold protein superfamily; This model and hierarchy represent the the substrate-binding domain of the LysR-type transcriptional regulators that form the largest family of prokaryotic transcription factor. Homologs of some of LTTRs with similar domain organizations are also found in the archaea and eukaryotic organisms. The LTTRs are 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. The genes controlled by the LTTRs have diverse functional roles including amino acid biosynthesis, CO2 fixation, antibiotic resistance, degradation of aromatic compounds, oxidative stress responses, nodule formation of nitrogen-fixing bacteria, synthesis of virulence factors, toxin production, attachment and secretion, to name a few. The structural topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2), which 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.

selenium metabolism-associated LysR family transcriptional regulator; LysR family transcriptional regulators regularly appear encoded adjacent to selenecysteine incorporation proteins such as SelB. This model represents one especially well-conserved subgroup of such transcription factors from species such as Merdimonas faecis, Sellimonas intestinalis, Syntrophotalea acetylenica, and Hydrogenivirga caldilitoris. Seed alignment members were selected by proximity to selB, but not all family members are expected to have similar genomic locations.

113-274 5.13e-13

The C-terminal substrate binding domain of LysR-type transcriptional regulators that are involved in the catabolism of dinitrotoluene, naphthalene and gamma-hexachlorohexane; contains the type 2 periplasmic binding fold; This CD includes LysR-like bacterial transcriptional regulators, DntR, NahR, and LinR, which are involved in the degradation of aromatic compounds. The transcription of the genes encoding enzymes involved in such degradation is regulated and expression of these enzymes is enhanced by inducers, which are either an intermediate in the metabolic pathway or compounds to be degraded. DntR from Burkholderia species controls genes encoding enzymes for oxidative degradation of the nitro-aromatic compound 2,4-dinitrotoluene. The active form of DntR is homotetrameric, consisting of a dimer of dimers. NahR is a salicylate-dependent transcription activator of the nah and sal operons for naphthalene degradation. Salicylic acid is an intermediate of the oxidative degradation of the aromatic ring in soil bacteria. LinR positively regulates expression of the genes (linD and linE) encoding enzymes for gamma-hexachlorocyclohexane (a haloorganic insecticide) degradation. Expression of linD and linE are induced by their substrates, 2,5-dichlorohydroquinone (2,5-DCHQ) and chlorohydroquinone (CHQ). The structural topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2), which 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.

113-299 9.75e-11

The C-terminal substrate binding domain of LysR-type transcriptional regulator TdcA, which is involved in the degradation of L-serine and L-threonine, contains the type 2 periplasmic binding fold; TdcA, a member of the LysR family, activates the expression of the anaerobically-regulated tdcABCDEFG operon which is involved in the degradation of L-serine and L-threonine to acetate and propionate, respectively. The tdc operon is comprised of one regulatory gene tdcA and six structural genes, tdcB to tdcG. The expression of the tdc operon is affected by several transcription factors including the cAMP receptor protein (CRP), integration host factor (IHF), histone-like protein (HU), and the operon specific regulators TdcA and TcdR. TcdR is divergently transcribed from the operon and encodes a small protein that is required for efficient expression of the Escherichia coli tdc operon. This substrate-binding domain shows significant homology to the type 2 periplasmic binding proteins (PBP2), which 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.

113-296 2.84e-09

C-terminal substrate binding domain of LysR-type transcriptional regulator CysL, which activates the transcription of the cysJI operon encoding sulfite reductase, contains the type 2 periplasmic binding fold; CysL, also known as YwfK, is a regular of sulfur metabolism in Bacillus subtilis. Sulfur is required for the synthesis of proteins and essential cofactors in all living organism. Sulfur can be assimilated either from inorganic sources (sulfate and thiosulfate), or from organic sources (sulfate esters, sulfamates, and sulfonates). CysL activates the transcription of the cysJI operon encoding sulfite reductase, which reduces sulfite to sulfide. Both cysL mutant and cysJI mutant are unable to grow using sulfate or sulfite as the sulfur source. Like other LysR-type regulators, CysL also negatively regulates its own transcription. In Escherichia coli, three LysR-type activators are involved in the regulation of sulfur metabolism: CysB, Cbl and MetR. The topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2), which 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.

115-296 1.45e-08

The C-terminal substrate-binding domain of the LysR-type transcriptional regulator CynR, contains the type 2 periplasmic binding fold; 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. The CynR of LysR-type transcriptional regulator family 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). 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.

108-202 4.92e-06

The substrate binding domain of LysR-type transcriptional regulator GltC, which activates gltA expression of glutamate synthase operon, contains type 2 periplasmic binding fold; GltC, a member of the LysR family of bacterial transcriptional factors, activates the expression of gltA gene of glutamate synthase operon and is essential for cell growth in the absence of glutamate. Glutamate synthase is a heterodimeric protein that encoded by gltA and gltB, whose expression is subject to nutritional regulation. GltC also negatively auto-regulates its own expression. This substrate-binding domain has strong homology to the type 2 periplasmic binding proteins (PBP2), which 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.

113-279 5.18e-06

The C-terminal substrate binding of LysR-type symbiotic regulator SyrM, which activates expression of nodulation gene NodD3, contains the type 2 periplasmic binding fold; 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), which 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.

106-281 1.10e-05

The C-terminal substrate binding domain of LysR-type transcriptional regulators involved in the catabolism of aromatic compounds and that of other related regulators, contains type 2 periplasmic binding fold; This CD includes the C-terminal substrate binding domain of LTTRs involved in degradation of aromatic compounds, such as CbnR, BenM, CatM, ClcR and TfdR, as well as that of other transcriptional regulators clustered together in phylogenetic trees, including XapR, HcaR, MprR, IlvR, BudR, AlsR, LysR, and OccR. The structural topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2), which 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.

104-182 1.10e-05

TThe C-terminal substrate binding domain of an uncharacterized LysR-type transcriptional regulator, contains the type 2 periplasmic binding fold; LysR-transcriptional regulators comprise the largest family of prokaryotic transcription factor. Homologs of some of LTTRs with similar domain organizations are also found in the archaea and eukaryotic organisms. The LTTRs are 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. The genes controlled by the LTTRs have diverse functional roles including amino acid biosynthesis, CO2 fixation, antibiotic resistance, degradation of aromatic compounds, nodule formation of nitrogen-fixing bacteria, and synthesis of virulence factors, to a name a few. This substrate-binding domain shows significant homology to the type 2 periplasmic binding proteins (PBP2), which 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.

109-296 3.51e-05

The C-terminal substrate binding domain of LysR-type transcriptional regulators, YofA and SoxR, contains the type 2 periplasmic binding fold; YofA is a LysR-like transcriptional regulator of cell growth in Bacillus subtillis. YofA controls cell viability and the formation of constrictions during cell division. YofaA positively regulates expression of the cell division gene ftsW, and thus is essential for cell viability during stationary-phase growth of Bacillus substilis. YofA shows significant homology to SoxR from Arthrobacter sp. TE1826. SoxR is a negative regulator for the sarcosine oxidase gene soxA. Sarcosine oxidase catalyzes the oxidative demethylation of sarcosine, which is involved in the metabolism of creatine and choline. The topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2), which 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.

The C-terminal substrate binding domain of an uncharacterized LysR-type transcriptional regulator similar to DntR, which is involved in the catabolism of dinitrotoluene; contains the type 2 periplasmic binding fold; This CD includes an uncharacterized LysR-type transcriptional regulator similar to DntR, NahR, and LinR, which are involved in the degradation of aromatic compounds. The transcription of the genes encoding enzymes involved in such degradation is regulated and expression of these enzymes is enhanced by inducers, which are either an intermediate in the metabolic pathway or compounds to be degraded. This substrate-binding domain shows significant homology to the type 2 periplasmic binding proteins (PBP2), which 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.

113-197 1.63e-03

The C-terminal substrate-binding domain of the LysR-type transcriptional regulator OxyR, a member of the type 2 periplasmic binding fold protein superfamily; OxyR senses hydrogen peroxide and is activated through the formation of an intramolecular disulfide bond. The OxyR activation induces the transcription of genes necessary for the bacterial defense against oxidative stress. The OxyR of LysR-type transcriptional regulator family 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. The C-terminal domain also contains the redox-active cysteines that mediate the redox-dependent conformational switch. Thus, the interaction between the OxyR-tetramer and DNA is notably different between the oxidized and reduced forms. The structural topology of this substrate-binding domain is most similar to that of the type 2 periplasmic binding proteins (PBP2), which 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.

135-274 4.22e-03

The C-terminal substrate binding domain of an uncharacterized LysR-type transcriptional regulator similar to DntR, which is involved in the catabolism of dinitrotoluene; contains the type 2 periplasmic binding fold; This CD includes an uncharacterized LysR-type transcriptional regulator similar to DntR, NahR, and LinR, which are involved in the degradation of aromatic compounds. The transcription of the genes encoding enzymes involved in such degradation is regulated and expression of these enzymes is enhanced by inducers, which are either an intermediate in the metabolic pathway or compounds to be degraded. This substrate-binding domain shows significant homology to the type 2 periplasmic binding proteins (PBP2), which 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.
