55-427 1.15e-39

The periplasmic-binding component of ABC transport system specific for sn-glycerol-3-phosphate; possesses type 2 periplasmic binding fold; This group includes the periplasmic component of an ABC transport system specific for sn-glycerol-3-phosphate (G3P) and closely related proteins from archaea and bacteria. Under phophate starvation conditions, Escherichia coli can utilize G3P as phosphate source when exclusively imported by an ATP-binding cassette (ABC) transporter composed of the periplasmic binding protein, UgpB, the transmembrane subunits, UgpA and UgpE, and a homodimer of the nucleotide binding subunit, UgpC. Members of this group belong to the type 2 periplasmic-binding fold superfamily. PBP2 proteins are 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.

The periplasmic-binding component of ABC transport systems specific for trehalose/maltose; possesses type 2 periplasmic binding fold; This group represents the periplasmic trehalose/maltose-binding component of an ABC transport system and related proteins from archaea and bacteria. Members of this group belong to the type 2 periplasmic-binding fold superfamily. PBP2 proteins are 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.

42-336 1.16e-13

The periplasmic-binding component of an uncharacterized ABC transport system from Rhodopseudomonas palustris CGA009 and related proteins; contains the type 2 periplasmic-binding fold; This group represents the periplasmic binding domain that serves as the primary high-affinity receptor of an uncharacterized ABC-type polyamine transporter from Rhodopseudomonas palustris Cga009 and related proteins from other bacteria. Polyamine transport plays an essential role in the regulation of intracellular polyamine levels which are known to be elevated in rapidly proliferating cells and tumors. Natural polyamines are putrescine, spermindine, and spermine. They are polycations that play multiple roles in cell growth, survival and proliferation, and plant stress and disease resistance. They can interact with negatively charged molecules, such as nucleic acids, to modulate their functions. Members of this family belong to the type 2 periplasmic-binding fold superfamily. PBP2 is 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.

42-424 2.20e-10

The periplasmic-binding component of ABC transport systems specific for maltose and related oligosaccharides; possess type 2 periplasmic binding fold; This family represents the periplasmic binding component of ABC transport systems involved in uptake of oligosaccharides including maltose, trehalose, maltodextrin, and cyclodextrin. Members of this family belong to the type 2 periplasmic-binding fold superfamily. PBP2 is 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.

48-336 2.32e-06

The periplasmic-binding component of ABC transporters involved in uptake of polyamines; possess the type 2 periplasmic binding fold; This family represents the periplasmic substrate-binding proteins that function as the primary high-affinity receptors of ABC-type polyamine transport systems. Polyamine transport plays an essential role in the regulation of intracellular polyamine levels which are known to be elevated in rapidly proliferating cells and tumors. Natural polyamines are putrescine, spermindine, and spermine. They are polycations that play multiple roles in cell growth, survival and proliferation, as well as plant stress and disease resistance. They can interact with negatively charged molecules, such as nucleic acids, to modulate their functions. Members of this family belong to the type 2 periplasmic-binding fold superfamily. PBP2 is 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.

40-336 1.59e-05

Periplasmic-binding component of alginate-specific ABC uptake system-like; contains the type 2 periplasmic binding fold; This subgroup includes uncharacterized periplasmic-binding proteins that are closely related to high molecular weight (HMW) alginate bining proteins (AlgQ1 and AlgQ2) found in gram-negative soil bacteria. The HMW alginate uptake system is composed of a novel pit formed on the cell surface and a pit-dependent ATP-binding cassette (ABC) transporter in the inner membrane. The transportation of HMW alginate from the pit to the ABC transporter is mediated by periplasmic HMW alginate-binding proteins (AlgQ1 and AlgQ2). Alginate is an anionic polysaccharide that is made up of alpha-L-mannuronate and its 5'-epimer, alpha-L-guluronate. Alginate is present in the cell walls of brown seaweeds, where it forms a viscous gum by binding water. Alginate is also produced by two bacteria genera Pseudomonas and Azotobacter. AlgQ1 and AlgQ2 belong to the type 2 periplasmic-binding fold superfamily. PBP2 is 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. However, unlike other bacterial periplasmic-binding proteins that deliver small solutes to ABC transporters, AlgQ1/2 can bind a macromolecule and may have specificity for either sugar or a certain type of polysaccharide.

Periplasmic-binding component of alginate-specific ABC uptake system-like; contains the type 2 periplasmic binding fold; This subgroup includes uncharacterized periplasmic-binding proteins that are closely related to high molecular weight (HMW) alginate bining proteins (AlgQ1 and AlgQ2) found in gram-negative soil bacteria. The HMW alginate uptake system is composed of a novel pit formed on the cell surface and a pit-dependent ATP-binding cassette (ABC) transporter in the inner membrane. The transportation of HMW alginate from the pit to the ABC transporter is mediated by periplasmic HMW alginate-binding proteins (AlgQ1 and AlgQ2). Alginate is an anionic polysaccharide that is made up of alpha-L-mannuronate and its 5'-epimer, alpha-L-guluronate. Alginate is present in the cell walls of brown seaweeds, where it forms a viscous gum by binding water. Alginate is also produced by two bacteria genera Pseudomonas and Azotobacter. AlgQ1 and AlgQ2 belong to the type 2 periplasmic-binding fold superfamily. PBP2 is 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. However, unlike other bacterial periplasmic-binding proteins that deliver small solutes to ABC transporters, AlgQ1/2 can bind a macromolecule and may have specificity for either sugar or a certain type of polysaccharide.

60-337 3.08e-04

The periplasmic substrate-binding component of an ABC putrescine transport system and related proteins; contains the type 2 periplasmic-binding fold; This group represents the periplasmic substrate-binding domain that serves as the primary polyamine receptor of ABC-type putrescine-preferential transporter from gram-negative bacteria. Polyamine transport plays an essential role in the regulation of intracellular polyamine levels which are known to be elevated in rapidly proliferating cells and tumors. Natural polyamines are putrescine, spermindine, and spermine. They are polycations that play multiple roles in cell growth, survival and proliferation, and plant stress and disease resistance. They can interact with negatively charged molecules, such as nucleic acids, to modulate their functions. Members of this family belong to the type 2 periplasmic-binding fold superfamily. PBP2 is 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.
