27-289 4.56e-68

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.

ABC transporter periplasmic binding protein, thiB subfamily; The model describes thiamine ABC transporter, periplasmic protein in bacteria and archae. The protein belongs to the larger ABC transport system. It consists of at least three components: the thiamine binding periplasmic protein; an inner membrane permease; an ATP-binding subunit. It has been experimentally demonstrated that the mutants in the various steps in the de novo synthesis of the thiamine and the biologically active form, namely thiamine pyrophosphate can be exogenously supplemented with thiamine, thiamine monophosphate (TMP) or thiamine pyrophosphate (TPP).

27-289 4.56e-68

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.

27-310 4.91e-33

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 domain that functions 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, 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.

89-339 5.86e-19

The periplasmic substrate-binding component of an active spermidine-preferential transport system; contains the type 2 periplasmic binding fold; This group represents the periplasmic binding domain that serves as the primary polyamine receptor of ABC-type spermindine-preferential transport system 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.

43-292 2.00e-17

Substrate binding domain of thiamin transporter, a member of the type 2 periplasmic binding fold superfamily; Thiamin-binding protein TbpA is the periplasmic component of ABC-type transporter in E. coli, while the transmembrane permease and ATPase are ThiP and ThiQ, respectively. Thiamin (vitamin B1) is an essential confactor in all living systems that most prokaryotes, plants, and fungi can synthesized thiamin. However, in vertebrates, thiamine cannot be synthesized and must therefore be obtained through dietary absorption. In addition to thiamin biosynthesis, most organisms can import thiamin using specific transporters. After binding thiamine with high affinity, TbpA interacts with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis. The thiamine-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.

40-297 3.90e-16

Substrate binding domain of iron and thiamine transporters-like, a member of the type 2 periplasmic binding fold superfamily; The periplasmic iron binding protein plays an essential role in the iron uptake pathway of Gram-negative pathogenic bacteria from the Pasteurellaceae and Neisseriaceae families and is critical for survival of these pathogens within the host. On the other hand, thiamin is an essential cofactor in all living systems. Thiamin diphosphate (ThDP)-dependent enzymes play an important role in carbohydrate and branched-chain amino acid metabolism. Most prokaryotes, plants, and fungi can synthesize thiamin, but it is not synthesized in vertebrates. These periplasmic domains have high affinities for their respective substrates and serve as the primary receptor for transport. After binding iron and thiamine with high affinity, they interact with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis. The iron- and thiamine-binding proteins belong to the PBPI2 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 periplasmic binding protein, thiB subfamily; The model describes thiamine ABC transporter, periplasmic protein in bacteria and archae. The protein belongs to the larger ABC transport system. It consists of at least three components: the thiamine binding periplasmic protein; an inner membrane permease; an ATP-binding subunit. It has been experimentally demonstrated that the mutants in the various steps in the de novo synthesis of the thiamine and the biologically active form, namely thiamine pyrophosphate can be exogenously supplemented with thiamine, thiamine monophosphate (TMP) or thiamine pyrophosphate (TPP).

27-336 7.92e-11

The periplasmic-binding component of ABC transport systems specific for trehalose/maltose and similar oligosaccharides; possess type 2 periplasmic binding fold; This family includes 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 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.

32-289 7.24e-09

Substrate binding domain of an uncharacterized ferric iron transporter, a member of the type 2 periplasmic binding fold superfamily; The periplasmic iron binding protein plays an essential role in the iron uptake pathway of Gram-negative pathogenic bacteria from the Pasteurellaceae and Neisseriaceae families and is critical for survival of these pathogens within the host. This periplasmic domain (Fbp) has high affinity for ferric iron and serves as the primary receptor for transport. After binding iron with high affinity, Fbp interacts with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis. The ferric iron-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.

36-282 9.72e-09

The periplasmic substrate-binding component of an ABC-type polyamine transport system from Treponema pallidum and related proteins; contains the type 2 periplasmic binding fold; This group includes the polyamine-binding component of an ABC-type polyamine transport system from Treponema pallidum and closely related proteins, which is homologous to the spermidine-preferring periplasmic substrate-binding protein component (PotD)of ABC transport system. 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.

40-302 6.04e-06

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.

41-330 5.16e-05

Substrate binding domain of ferric iron-binding protein, a member of the type 2 periplasmic binding fold superfamily; FutA1 is the periplasmic component of an ABC-type iron transporter and serves as the primary receptor in Synerchosystis species. The periplasmic iron binding protein plays an essential role in the iron uptake pathway of Gram-negative pathogenic bacteria and is critical for survival of these pathogens within the host. After binding iron with high affinity, FutA1 interact with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis. The iron- and thiamine-binding proteins belong to the PBPI2 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.

28-298 8.28e-04

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.

123-321 1.24e-03

The periplasmic substrate-binding component of an uncharacterized active transport system closely related to spermidine and putrescine transporters; contains the type 2 periplasmic binding fold; This group represents the periplasmic binding domain that serves as a primary polyamine receptor of an uncharacterized ABC-type transport system from plants and plant-symbiotic cyanobacteria. 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.
