27-323 2.90e-135

Uncharacterized substrate-binding protein of the Tripartite ATP-independent Periplasmic transporter family; the type 2 periplasmic-binding protein fold; This subfamily includes uncharacterized periplasmic substrate-binding proteins similar to TRAP transport systems such as SiaP (a sialic acid binding virulence factor) and TeaA (an ectoine binding protein). TRAP transporters are a large family of solute transporters ubiquitously found in bacteria and archaea. They are comprised of a periplasmic substrate-binding protein (SBP) and two unequally sized integral membrane components: a large transmembrane subunit involved in the translocation process and a smaller membrane of unknown function. The driving force of TRAP transporters is provided by electrochemical ion gradients (either protons or sodium ions) across the cytoplasmic membrane, rather than ATP hydrolysis. 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.

32-309 3.31e-81

Bacterial extracellular solute-binding protein, family 7; This family of proteins is involved in binding extracellular solutes for transport across the bacterial cytoplasmic membrane. This family includes Swiss:P37735, a C4-dicarboxylate-binding protein and the sialic acid-binding protein SiaP. The structure of the SiaP receptor has revealed an overall topology similar to ATP binding cassette ESR (extracytoplasmic solute receptors) proteins. Upon binding of sialic acid, SiaP undergoes domain closure about a hinge region and kinking of an alpha-helix hinge component.

33-274 6.82e-62

tripartite ATP-independent periplasmic transporter solute receptor, DctP family; TRAP-T (Tripartite ATP-independent Periplasmic Transporter) family proteins generally consist of three components, and these systems have so far been found in Gram-negative bacteria, Gram-postive bacteria and archaea. The best characterized example is the DctPQM system of Rhodobacter capsulatus, a C4 dicarboxylate (malate, fumarate, succinate) transporter. This model represents the DctP family, one of at least three major families of extracytoplasmic solute receptor for TRAP family transporters. Other are the SnoM family (see pfam03480) and TAXI (TRAP-associated extracytoplasmic immunogenic) family. [Transport and binding proteins, Carbohydrates, organic alcohols, and acids]

27-323 2.90e-135

Uncharacterized substrate-binding protein of the Tripartite ATP-independent Periplasmic transporter family; the type 2 periplasmic-binding protein fold; This subfamily includes uncharacterized periplasmic substrate-binding proteins similar to TRAP transport systems such as SiaP (a sialic acid binding virulence factor) and TeaA (an ectoine binding protein). TRAP transporters are a large family of solute transporters ubiquitously found in bacteria and archaea. They are comprised of a periplasmic substrate-binding protein (SBP) and two unequally sized integral membrane components: a large transmembrane subunit involved in the translocation process and a smaller membrane of unknown function. The driving force of TRAP transporters is provided by electrochemical ion gradients (either protons or sodium ions) across the cytoplasmic membrane, rather than ATP hydrolysis. 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.

Bacterial extracellular solute-binding protein, family 7; This family of proteins is involved in binding extracellular solutes for transport across the bacterial cytoplasmic membrane. This family includes Swiss:P37735, a C4-dicarboxylate-binding protein and the sialic acid-binding protein SiaP. The structure of the SiaP receptor has revealed an overall topology similar to ATP binding cassette ESR (extracytoplasmic solute receptors) proteins. Upon binding of sialic acid, SiaP undergoes domain closure about a hinge region and kinking of an alpha-helix hinge component.

27-323 1.30e-65

Periplasmic component of TRAP-type C4-dicarboxylate transport system TM0322 from Thermotoga maritima and similar proteins; the type 2 periplasmic binding protein fold; This subgroup includes the hyperthermophilic bacterium Thermotoga maritima TRAP-type C4-dicarboxylate transport system TM0322 and its closely related proteins. TRAP transporters are a large family of solute transporters ubiquitously found in bacteria and archaea. They are comprised of a periplasmic substrate-binding protein (SBP; often called the P subunit) and two unequally sized integral membrane components: a large transmembrane subunit involved in the translocation process (the M subunit) and a smaller membrane of unknown function (the Q subunit). The driving force of TRAP transporters is provided by electrochemical ion gradients (either protons or sodium ions) across the cytoplasmic membrane, rather than ATP hydrolysis. 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.

33-274 6.82e-62

tripartite ATP-independent periplasmic transporter solute receptor, DctP family; TRAP-T (Tripartite ATP-independent Periplasmic Transporter) family proteins generally consist of three components, and these systems have so far been found in Gram-negative bacteria, Gram-postive bacteria and archaea. The best characterized example is the DctPQM system of Rhodobacter capsulatus, a C4 dicarboxylate (malate, fumarate, succinate) transporter. This model represents the DctP family, one of at least three major families of extracytoplasmic solute receptor for TRAP family transporters. Other are the SnoM family (see pfam03480) and TAXI (TRAP-associated extracytoplasmic immunogenic) family. [Transport and binding proteins, Carbohydrates, organic alcohols, and acids]

27-320 1.38e-51

Substrate-binding component of Tripartite ATP-independent Periplasmic transporter DctP10; the type 2 periplasmic-binding protein fold; This subgroup includes TRAP transporter DctP10 and its similar proteins. TRAP transporters are a large family of solute transporters ubiquitously found in bacteria and archaea. They are comprised of a periplasmic substrate-binding protein (SBP; often called the P subunit) and two unequally sized integral membrane components: a large transmembrane subunit involved in the translocation process (the M subunit) and a smaller membrane of unknown function (the Q subunit). The driving force of TRAP transporters is provided by electrochemical ion gradients (either protons or sodium ions) across the cytoplasmic membrane, rather than ATP hydrolysis. 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.

27-307 1.68e-36

Periplasmic substrate-binding component of TRAP-type C4-dicarboxylate transport system DctP3 and DctP4; the type 2 periplasmic-binding protein fold; This group includes uncharacterized DctP3 and DctP 4 subfamilies of TRAP Transporters specific to C4-dicarboxylates such as succinate, malate and fumarate. TRAP transporters are a large family of solute transporters ubiquitously found in bacteria and archaea. This CD also included some eukaryotic homologs that have not been functionally characterized. TRAP transporters are comprised of a periplasmic substrate-binding protein (SBP; often called the P subunit) and two unequally sized integral membrane components: a large transmembrane subunit involved in the translocation process (the M subunit) and a smaller membrane of unknown function (the Q subunit). The driving force of TRAP transporters is provided by electrochemical ion gradients (either protons or sodium ions) across the cytoplasmic membrane, rather than ATP hydrolysis. 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.

46-306 4.37e-28

Substrate-binding component of Tripartite ATP-independent Periplasmic transporters and related proteins; contains the type 2 periplasmic-binding protein fold; This family represents the TRAP Transporters that are specific to various ligands, including sialic acid (N-acetyl neuraminic acid), glutamate, ectoine, xylulose, C4-dicarboxylates such as succinate, malate and fumarate, and keto acids such as pyruvate and alpha-ketobutyrate. TRAP transporters are a large family of solute transporters ubiquitously found in bacteria and archaea. This family also includes some eukaryotic homologs that have not been functionally characterized. TRAP transporters are comprised of a periplasmic substrate-binding protein (SBP; often called the P subunit) and two unequally sized integral membrane components: a large transmembrane subunit involved in the translocation process (the M subunit) and a smaller membrane of unknown function (the Q subunit). The driving force of TRAP transporters is provided by electrochemical ion gradients (either protons or sodium ions) across the cytoplasmic membrane, rather than ATP hydrolysis. 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.

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.

140-265 5.25e-06

Substrate binding domain of ABC-type nitrate/sulfonate/bicarbonate transporters, a member of the type 2 periplasmic binding fold superfamily; This family represents the periplasmic binding proteins involved in nitrate, alkanesulfonate, and bicarbonate transport. These domains are found in eubacterial perisplamic-binding proteins that serve as initial receptors in the ABC transport of bicarbonate, nitrate, taurine, or a wide range of aliphatic sulfonates. Other closest homologs involved in thiamine (vitamin B1) biosynthetic pathway and desulfurization (DszB) are also included in this family. After binding their ligand with high affinity, they 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. These binding 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.

ABC transporter, substrate-binding protein, aliphatic sulfonates family; Members of this family are substrate-binding periplasmic proteins of ABC transporters. This subfamily includes SsuA, a member of a transporter operon needed to obtain sulfur from aliphatic sulfonates. Related proteins outside the scope of this model include taurine (NH2-CH2-CH2-S03H) binding proteins, the probable sulfate ester binding protein AtsR, and the probable aromatic sulfonate binding protein AsfC. All these families make sulfur available when Cys and sulfate levels are low. Please note that phylogenetic analysis by neighbor-joining suggests that a number of sequences belonging to this family have been excluded because of scoring lower than taurine-binding proteins.

Taurine-binding periplasmic protein; the type 2 periplasmic binding protein fold; This subfamily includes the periplasmic component of putative ABC-type sulfonate transport system similar to SsuA. These domains are found in eubacterial SsuA proteins that serve as initial receptors in the ABC transport of bicarbonate, nitrate, taurine, or a wide range of aliphatic sulfonates, while other closest homologs are involved in thiamine (vitamin B1) biosynthetic pathway and desulfurization (DszB). After binding the ligand, SsuA interacts 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 SsuA 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.

155-217 8.53e-03

Substrate binding domain of phosphonate uptake system-like, a member of the type 2 periplasmic-binding fold superfamily; This family includes alkylphosphonate binding domain PhnD. These domains are found in PhnD-like proteins that are predicted to function as initial receptors in hypophosphite, phosphonate, or phosphate ABC transport in archaea and eubacteria. PhnD is the periplasmic binding component of an ABC-type phosphonate uptake system (PhnCDE) that recognizes and binds phosphonate. PhnD belongs 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. The PBP2 have been shown to bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.
