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 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).

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.

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.

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. Pssm-ID: 176153 [Multi-domain] Cd Length: 200 Bit Score: 37.21 E-value: 5.56e-03
