The C-terminal substrate binding domain of LysR-type transcriptional regulator CrgA and its related homologs, contains the type 2 periplasmic binding domain; This CD includes the substrate binding domain of LysR-type transcriptional regulator (LTTR) CrgA and its related homologs. The LTTRs are acting as both auto-repressors and activators of target promoters, controlling operons involved in a wide variety of cellular processes such as amino acid biosynthesis, CO2 fixation, antibiotic resistance, degradation of aromatic compounds, nodule formation of nitrogen-fixing bacteria, and synthesis of virulence factors, to name a few. In contrast to the tetrameric form of other LTTRs, CrgA from Neisseria meningitides assembles into an octameric ring, which can bind up to four 63-bp DNA oligonucleotides. Phylogenetic cluster analysis further showed that the CrgA-like regulators form a subclass of the LTTRs that function as octamers. The CrgA is an auto-repressor of its own gene and activates the expression of the mdaB gene which coding for an NADPH-quinone reductase and that its action is increased by MBL (alpha-methylene-gamma-butyrolactone), an inducer of NADPH-quinone oxidoreductase. 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. : Pssm-ID: 176114 [Multi-domain] Cd Length: 197 Bit Score: 196.89 E-value: 2.27e-64

The CrgA is an auto-repressor of its own gene and activates the expression of the mdaB gene which coding for an NADPH-quinone reductase and that its action is increased by MBL (alpha-methylene-gamma-butyrolactone), an inducer of NADPH-quinone oxidoreductase. 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. Pssm-ID: 176167 [Multi-domain] Cd Length: 199 Bit Score: 90.09 E-value: 1.56e-22

The C-terminal substrate-domain of LysR-type transcriptional regulators for beta-lactamase genes, contains the type 2 periplasmic binding fold; This CD includes the C-terminal substrate binding domain of LysR-type transcriptional regulators, BlaA and AmpR, that are involved in control of the expression of beta-lactamase genes. Beta-lactamases are responsible for bacterial resistance to beta-lactam antibiotics such as penicillins. BlaA (a constitutive class A penicillinase) belongs to the LysR family of transcriptional regulators, while 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. AmpR regulates the expression of beta-lactamases in many enterobacterial strains and many other gram-negative bacilli. In contrast to BlaA, AmpR acts an activator only in the presence of the beta-lactam inducer. In the absence of the inducer, AmpR acts as a repressor. 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.

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 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.

The C-terminal substrate domain of LysR-type transcriptional regulator AmpR that involved in control of the expression of beta-lactamase gene ampC, contains the type 2 periplasmic binding fold; AmpR acts as a transcriptional activator by binding to a DNA region immediately upstream of the ampC promoter. In the absence of a beta-lactam inducer, AmpR represses the synthesis of beta-lactamase, whereas expression is induced in the presence of a beta-lactam inducer. The AmpD, AmpG, and AmpR proteins are involved in the induction of AmpC-type beta-lactamase (class C) which produced by enterobacterial strains and many other gram-negative bacilli. The activation of ampC by AmpR requires ampG for induction or high-level expression of AmpC. It is probable that the AmpD and AmpG work together to modulate the ability of AmpR to activate ampC expression. 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.
