30-259 3.70e-101

Substrate binding domain of an ABC transporter TcyJKLMN; the type 2 periplasmic binding protein fold; This group contains periplasmic cystine-binding domain (TcyK) of an ATP-binding cassette transporter from Bacillus subtilus and its closely related proteins. Cystine is an oxidized dimeric form of cysteine that is required for optimal bacterial growth. In Bacillus subtilis, three ABC transporters, TcyJKLMN (YtmJKLMN), TcyABC (YckKJI), and YxeMNO are involved in uptake of cystine. Likewise, three uptake systems were identified in Salmonella enterica serovar Typhimurium, while in Escherichia coli, two transport systems seem to be involved in cystine uptake. Moreover, L-cystine limitation was shown to prevent virulence of Neisseria gonorrhoeae; thus, its L-cystine solute receptor (Ngo0372) may be suited as target for an antimicrobial vaccine. The cystine receptor belongs to the type 2 periplasmic binding fold protein superfamily (PBP2). The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and 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 receptor cytoplasmically-located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.

Substrate binding domain of cystine ABC transporters; the type 2 periplasmic binding protein fold; Cystine-binding domain of periplasmic receptor-dependent ATP-binding cassette (ABC) transporters. Cystine is an oxidized dimeric form of cysteine that is required for optimal bacterial growth. In Bacillus subtilis, three ABC transporters, TcyJKLMN (YtmJKLMN), TcyABC (YckKJI), and YxeMNO are involved in uptake of cystine. Also, three uptake systems were identified in Salmonella enterica serovar Typhimurium, while in Escherichia coli, two transport systems seem to be involved in cystine uptake. Moreover, L-cystine limitation was shown to prevent virulence of Neisseria gonorrhoeae; thus, its L-cystine solute receptor (Ngo0372) may be suited as target for an antimicrobial vaccine. The cystine receptor belongs to the type 2 periplasmic binding fold protein superfamily (PBP2). The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and 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 receptor cytoplasmically-located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.

31-253 2.59e-40

Peptide-binding protein and related homologs; type 2 periplasmic binding protein fold; This domain is found in solute binding proteins that serve as initial receptors in the ABC transport, signal transduction and channel gating. The PBP2 proteins share the same architecture as periplasmic binding proteins type 1, but have a different topology. They are typically comprised of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. The majority of PBP2 proteins function in the uptake of small soluble substrates in eubacteria and archaea. 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 family includes ionotropic glutamate receptors and unorthodox sensor proteins involved in signal transduction.

31-254 1.49e-33

Substrate binding domain of the arginine-, lysine-, histidine-binding protein ArtJ; the type 2 periplasmic binding protein fold; This group includes the periplasmic substrate-binding protein ArtJ of the ATP-binding cassette (ABC) transport system from the thermophilic bacterium Geobacillus stearothermophilus, which is specific for arginine, lysine, and histidine. ArtJ belongs to the type 2 periplasmic-binding fold protein (PBP2) superfamily, whose members are involved in chemotaxis and uptake of nutrients and other small molecules from the extracellular space as a primary receptor. PBP2 typically comprises of two globular subdomains connected by a flexible hinge and 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 receptor cytoplasmically-located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.

31-255 2.00e-29

Substrate binding domain of an Escherichia coli ABC transporter; the type 2 periplasmic binding protein fold; This group contains cystine binding domain FliY and its related proteins. Cystine is an oxidized dimeric form of cysteine that is required for optimal bacterial growth. In Bacillus subtilis, three ABC transporters, TcyJKLMN (YtmJKLMN), TcyABC (YckKJI), and YxeMNO are involved in uptake of cystine. Likewise, three uptake systems were identified in Salmonella enterica serovar Typhimurium, while in Escherichia coli, two transport systems seem to be involved in cystine uptake. Moreover, L-cystine limitation was shown to prevent virulence of Neisseria gonorrhoeae; thus, its L-cystine solute receptor (Ngo0372) may be suited as target for an antimicrobial vaccine. The cystine receptor belongs to the type 2 periplasmic binding fold protein superfamily (PBP2). The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and 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 receptor cytoplasmically-located ATPase domains.

In Bacillus subtilis, three ABC transporters, TcyJKLMN (YtmJKLMN), TcyABC (YckKJI), and YxeMNO are involved in uptake of cystine. Likewise, three uptake systems were identified in Salmonella enterica serovar Typhimurium, while in Escherichia coli, two transport systems seem to be involved in cystine uptake. Moreover, L-cystine limitation was shown to prevent virulence of Neisseria gonorrhoeae; thus, its L-cystine solute receptor (Ngo0372) may be suited as target for an antimicrobial vaccine. The cystine receptor belongs to the type 2 periplasmic binding fold protein superfamily (PBP2). The PBP2 proteins are typically comprises of two globular subdomains connected by a flexible hinge and 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 receptor cytoplasmically-located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.

29-249 4.00e-19

The periplasmic sensor domain of histidine kinase receptors; the type 2 periplasmic binding fold protein; This subfamily includes the periplasmic sensor domain of the histidine kinase receptors (HisK) which are elements of the two-component signal transduction systems commonly found in bacteria and lower eukaryotes. Typically, the two-component system consists of a membrane-spanning histidine kinase sensor and a cytoplasmic response regulator. The two-component systems serve as a stimulus-response coupling mechanism to enable microorganisms to sense and respond to changes in environmental conditions. Extracellular stimuli such as small molecule ligands and ions are detected by the N-terminal periplasmic sensing domain of the sensor kinase receptor, which regulate the catalytic activity of the cytoplasmic kinase domain and promote ATP-dependent autophosphorylation of a conserved histidine residue. The phosphate is then transferred to a conserved aspartate in the response regulator through a phospho-transfer mechanism, and the activity of the response regulator is in turn regulated. The sensor domain belongs to the type 2 periplasmic-binding fold protein (PBP2) superfamily, whose members are involved in chemotaxis and uptake of nutrients and other small molecules from the extracellular space through their function as an initial high-affinity binding component. PBP2 typically comprises of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

45-255 8.40e-18

The solute binding domain of YfhD proteins, a member of the type 2 periplasmic binding fold protein superfamily; This subfamily includes the solute binding domain YfhD_N. These domains are found in the YfhD proteins that are predicted to function as lytic transglycosylases that cleave the glycosidic bond between N-acetylmuramic acid and N-acetylglucosamin in peptidoglycan, while the YfhD_N domain might act as an auxiliary or regulatory subunit. In addition to periplasmic solute binding domain, they have an SLT domain, typically found in soluble lytic transglycosylases, and a C-terminal low complexity domain. The YfhD proteins might have been recruited to create localized cell wall openings required for transport of large substrates such as DNA. They belong to the PBP2 superfamily of periplasmic binding proteins that differ in size and ligand specificity, but have similar tertiary structures consisting of two globular subdomains connected by a flexible hinge. They have been shown to bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

28-249 5.08e-16

Substrate binding domain of ectoine/hydroxyectoine specific ABC transport system; the type 2 periplasmic binding protein fold; This family represents the periplasmic substrate-binding component of ABC transport systems that involved in uptake of osmoprotectants (also termed compatible solutes) such as ectoine and hydroxyectoine. To counteract the efflux of water, bacteria and archaea accumulate the compatible solutes for a sustained adjustment to high osmolarity surroundings. This substrate-binding domain belongs to the type 2 periplasmic binding fold protein superfamily (PBP2). The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

28-254 1.52e-14

Cyclohexadienyl dehydratase, a member of the type 2 periplasmic binding fold protein superfamily; This subfamily includes cyclohexadienyl dehydratase PheC. These proteins catalyze the decarboxylation of prephenate to phenylpyruvate in the alternative phenylalanine biosynthesis pathway in some proteobacteria and archaea. The PheC proteins belong to the PBPII superfamily of periplasmic binding proteins that differ in size and ligand specificity, but have similar tertiary structures consisting of two globular subdomains connected by a flexible hinge. They have been shown to bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. Since they the PheC proteins are so similar to periplasmic binding proteins, (PBP), it is evolutionarily plausible that several pre-existing PBP proteins might have been recruited to perform the enzymatic function.

Bacterial GluR0 ligand-binding domain; the type 2 periplasmic binding protein fold; Glutamate receptor domain GluR0. These domains are found in the GluR0 proteins that have been shown to function as prokaryotic L-glutamate activated potassium channels, also known ionotropic glutamate receptors or iGluRs. In addition to two ligand binding core domains, iGluRs typically have a channel-like domain inserted in the middle of the GluR-like domain. The GluR0 proteins belong to the PBP2 superfamily of periplasmic binding proteins that differ in size and ligand specificity, but have similar tertiary structures consisting of two globular subdomains connected by a flexible hinge. They have been shown to bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

30-254 2.76e-14

Substrate binding domain of an arginine 3rd transport system; the type 2 periplasmic binding fold; This subgroup is similar to the HisJ-like family that comprises the periplasmic substrate-binding proteins, including the lysine-, arginine-, ornithine-binding protein (LAO) and the histidine-binding protein (HisJ), which serve as initial receptors for active transport. HisJ and LAO proteins belong to the type 2 periplasmic-binding fold protein (PBP2) superfamily, whose members are involved in chemotaxis and uptake of nutrients and other small molecules from the extracellular space as a primary receptor. PBP2 typically comprises of two globular subdomains connected by a flexible hinge and 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 receptor cytoplasmically-located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.

30-240 5.16e-14

The type 2 periplasmic ligand-binding protein domain of the sensor-kinase BvgS and histidine kinase receptors, and related proteins; This family comprises the periplasmic sensor domain of the two-component sensor-kinase systems, such as the sensor protein BvgS of Bordetella pertussis and histidine kinase receptors (HisK), and uncharacterized related proteins. Typically, the two-component system consists of a membrane spanning sensor-kinase and a cytoplasmic response regulator. It serves as a stimulus-response coupling mechanism to enable microorganisms to sense and respond to changes in environmental conditions. The N-terminal sensing domain of the sensor kinase detects extracellular signals, such as small molecule ligands and ions, which then modulate the catalytic activity of the cytoplasmic kinase domain through a phosphorylation cascade. The periplasmic sensor domain belongs to the type 2 periplasmic-binding fold protein (PBP2) superfamily, whose members are involved in chemotaxis and uptake of nutrients and other small molecules from the extracellular space as a primary receptor. PBP2 typically comprises of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

Amino acid-binding domain of the type 2 periplasmic binding fold superfamily; This subfamily includes the periplasmic binding protein type II (BPBII). This domain is found in solute binding proteins that serve as initial receptors in the ABC transport, signal transduction and channel gating. The PBPII proteins share the same architecture as periplasmic binding proteins type I (PBPI), but have a different topology. They are typically comprised of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. The majority of PBPII proteins function in the uptake of small soluble substrates in eubacteria and archaea. 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 family includes ionotropic glutamate receptors and unorthodox sensor proteins involved in signal transduction.

30-254 2.24e-13

Substrate-binding domain of ABC aspartate-glutamate transporter; the type 2 periplasmic binding protein fold; This subfamily represents the periplasmic-binding protein component of ABC transporter specific for carboxylic amino acids, including GtlI from Escherichia coli. The aspartate-glutamate binding domain belongs to the type 2 periplasmic binding protein fold superfamily (PBP2), whose many members are involved in chemotaxis and uptake of nutrients and other small molecules from the extracellular space as a primary receptor. The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and 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 receptor cytoplasmically-located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.

28-255 2.65e-09

Substrate binding domain of ABC glutamate transporter; the type 2 periplasmic binding protein fold; This group includes periplasmic glutamate-binding domain GluB from Corynebacterium efficiens and its related proteins. The GluB domain belongs to the type 2 periplasmic binding protein fold superfamily (PBP2), whose many members are involved in chemotaxis and uptake of nutrients and other small molecules from the extracellular space as a primary receptor. The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and 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 receptor cytoplasmically-located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.

29-138 5.80e-08

The second of the two tandem periplasmic domains of sensor-kinase BvgS; the type 2 peripasmic-binding fold protein; This group contains the second domain of the periplasmic solute-binding domains of BvgS and related proteins. BvgS is composed of two periplasmic domains homologous to bacterial periplasmic-binding proteins (PBPs), a transmembrane region followed successively by a cytoplasmic PAS (Per/ARNT/SIM), a Histidine-kinase (HK), a receiver and a Histidine phosphotransfer (Hpt) domains. The sensor protein BvgS can autophosphorylate and phosphorylate the response regulator BvgA. The BvgAS phosphorelay controls the expression of virulence factors in response to certain environmental stimuli in Bordetella pertussis. Its close homologs, Escherichia coli EvgS and Klebsiella pneumoniae KvgS, appear to be involved in the transcriptional regulation of drug efflux pumps and in countering free radical stresses and sensing iron limiting conditions, respectively. The periplasmic sensor domain of BvgS belongs to the type 2 periplasmic-binding fold protein (PBP2) superfamily, whose members are involved in chemotaxis and uptake of nutrients and other small molecules from the extracellular space as a primary receptor. PBP2 typically comprises of two globular subdomains connected by a flexible hinge and 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 receptor cytoplasmically-located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.

Putative sensor domain similar to HisK; the type 2 periplasmic binding fold protein; This group includes periplasmic sensor domain of the histidine kinase receptors (HisK) which are elements of the two-component signal transduction systems commonly found in bacteria and lower eukaryotes. Typically, the two-component system consists of a membrane-spanning histidine kinase sensor and a cytoplasmic response regulator. The two-component systems serve as a stimulus-response coupling mechanism to enable microorganisms to sense and respond to changes in environmental conditions. Extracellular stimuli such as small molecule ligands and ions are detected by the N-terminal periplasmic sensing domain of the sensor kinase receptor, which regulate the catalytic activity of the cytoplasmic kinase domain and promote ATP-dependent autophosphorylation of a conserved histidine residue. The phosphate is then transferred to a conserved aspartate in the response regulator through a phospho-transfer mechanism, and the activity of the response regulator is in turn regulated. The sensor domain belongs to the type 2 periplasmic-binding fold protein (PBP2) superfamily, whose members are involved in chemotaxis and uptake of nutrients and other small molecules from the extracellular space through their function as an initial high-affinity binding component. PBP2 typically comprises of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

Substrate binding domain of polar amino-acid uptake ABC transporter; the type 2 periplasmic binding protein fold; This group includes the periplamic-binding protein component of putative polar amino acid ABC transporter. The polar amino-acid binding domain belongs to the type 2 periplasmic binding protein fold superfamily (PBP2), whose many members are involved in chemotaxis and uptake of nutrients and other small molecules from the extracellular space as a primary receptor. The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and 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 receptor cytoplasmically-located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.
