27-262 6.26e-133

Substrate bindng domain of ABC glutamate/glutamine/aspartate/asparagine transporter; the type 2 periplasmic binding protein fold; BztA is the periplamic-binding protein component of ABC transporter specific for carboxylic amino acids, glutamine and asparagine. The BZtA 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.

27-262 6.26e-133

Substrate bindng domain of ABC glutamate/glutamine/aspartate/asparagine transporter; the type 2 periplasmic binding protein fold; BztA is the periplamic-binding protein component of ABC transporter specific for carboxylic amino acids, glutamine and asparagine. The BZtA 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.

27-259 4.32e-60

Substrate-binding domain of cysteine- and aspartate/glutamate-binding proteins; the type 2 periplasmic-binding protein fold; This family comprises of the periplasmic-binding protein component of ABC transporters specific for cysteine and carboxylic amino acids, as well as their closely related proteins. The cysteine and aspartate-glutamate binding domains belong 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.

27-241 9.50e-28

Substrate binding domain of ABC cysteine transporter; the type 2 periplasmic binding protein fold; This subfamily comprises of the periplasmic-binding protein component of ABC transporter specific for cysteine and its closely related proteins. The cysteine-binding domains belong 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.

35-248 1.06e-23

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.

35-236 1.73e-14

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.

39-239 6.18e-14

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.

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.

Glutamine binding domain of ABC-type transporter; the type 2 periplasmic binding protein fold; This periplasmic substrate-binding component serves as an initial receptor in the ABC transport of glutamine in bacteria and eukaryota. GlnH 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.

47-250 1.33e-09

Substrate binding domain of putative ABC transporters involved in cystine import; the type 2 periplasmic binding protein fold; This group contains uncharacterized periplasmic cystine-binding domain of 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. 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.

47-235 1.86e-07

Substrate binding domain of ABC-type histidine/lysine/arginine/ornithine transporters and related proteins; the type 2 periplasmic-binding protein fold; This family 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.

47-234 7.17e-05

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.

25-229 3.46e-04

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.

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.
