25-320 2.20e-144

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.

28-283 1.48e-81

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]

25-320 2.20e-144

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.

25-320 1.06e-108

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.

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.

28-283 1.48e-81

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]

25-308 8.27e-81

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.

25-309 4.93e-58

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.

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.

37-292 1.19e-35

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.

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.

Substrate-binding component of Tripartite ATP-independent Periplasmic transporter DctP5 and related proteins; the type 2 periplasmic-binding protein fold; This subgroup includes TRAP transporter DctP5 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.

NMT1/THI5 like; This family contains the NMT1 and THI5 proteins. These proteins are proposed to be required for the biosynthesis of the pyrimidine moiety of thiamine.3]. They are regulated by thiamine. The protein adopts a fold related to the periplasmic binding protein (PBP) family. Both pyridoxal-5'-phosphate (PLP) and an iron atom are bound to the protein suggesting numerous residues of the active site necessary for HMP-P biosynthesis. The yeast protein is a dimer and, although exceptionally using PLP as a substrate, has notable similarities with enzymes dependent on this molecule as a cofactor.
