46-344 2.19e-175

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.

49-305 2.22e-134

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]

49-331 1.33e-128

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.

46-344 2.19e-175

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.

49-305 2.22e-134

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]

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.

Substrate-binding domain of a sialic acid binding Tripartite ATP-independent Periplasmic transport system (SiaP) and related proteins; the type 2 periplasmic-binding protein fold; This subfamily includes the periplasmic-binding component of TRAP transport systems such as SiaP (a sialic acid binding virulence factor), TeaA (an ectoine binding protein), and an uncharacterized TM0322 from hyperthermophilic bacterium Thermotoga maritima. 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.

46-340 4.11e-87

Substrate-binding component of Tripartite ATP-independent Periplasmic transporter DctP2 and related proteins; the type 2 periplasmic-binding protein fold; This subgroup includes TRAP transporter DctP2 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.

46-344 4.29e-55

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.

Periplasmic substrate-binding component of uncharacterized TRAP-type C4-dicarboxylate transporter subfamilies; the type 2 periplasmic-binding protein fold; This model includes uncharacterized DctP subfamilies of the TRAP Transporters. 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.

This substrate-binding domain belongs to the PBP2 superfamily. 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.
