41-341 4.42e-111

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.

42-328 1.49e-44

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.

43-297 4.10e-24

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]

41-341 4.42e-111

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.

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 pyroglutamic acid binding DctP subfamily of the tripartite ATP-independent periplasmic transporters; contains the type 2 periplasmic binding protein fold; DctP6 and DctP7 groups of the TRAP transporters that involved in pyroglutamic acid transport. 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.

39-334 1.43e-37

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.

Uncharacterized substrate-binding protein of the Tripartite ATP-independent Periplasmic transporter family; the type 2 periplasmic-binding protein fold; This subfamily includes the putative periplasmic substrate-binding protein Tp0957 from Treponema pallidum, which is 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.

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.

39-348 2.17e-27

Substrate-binding component of uncharacterized Tripartite ATP-independent Periplasmic transporter; 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 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.

43-297 4.10e-24

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]

PBP2_TRAP_lactate cd13681
Substrate-binding component of a lactate binding Tripartite ATP-independent Periplasmic ...
60-340 5.39e-22

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

Substrate-binding component of an alpha-keto acid binding Tripartite ATP-independent Periplasmic transporter and related proteins; contains the type 2 periplasmic-binding protein fold; This subgroup includes TRAP transporters that bind to ketoacids such as pyruvate and alpha-ketobutyrate, xylulose, and other unknown ligands. 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).
