Molybdate transport system is comprised of a periplasmic binding protein, an integral membrane protein, and an energizer protein. These three proteins are coded by modA, modB, and modC genes, respectively. ModA proteins serve as initial receptors in the ABC transport of molybdate mostly in eubacteria and archaea. Bacteria and archaea import molybdenum and tungsten from the environment in the form of the oxyanions molybdate (MoO(4) (2-)) and tungstate (WO(4) (2-)). After binding molybdate 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. In contrast to the structure of the two ModA homologs from Escherichia coli and Azotobacter vinelandii, where the oxygen atoms are tetrahedrally arranged around the metal center, the structure of Pyrococcus furiosus ModA/WtpA (PfModA) has revealed a binding site for molybdate and tungstate where the central metal atom is in a hexacoordinate configuration. This octahedral geometry was rather unexpected. The ModA 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.

33-246 9.62e-08

molybdenum ABC transporter, periplasmic molybdate-binding protein; The model describes the molybdate ABC transporter periplasmic binding protein in bacteria and archae. Several of the periplasmic receptors constitute a diverse class of binding proteins that differ widely in size, sequence and ligand specificity. It has been shown experimentally by radioactive labeling that ModA represent hydrophylioc periplasmic-binding protein in gram-negative organisms and its counterpart in gram-positive organisms is a lipoprotein. The other components of the system include the ModB, an integral membrane protein and ModC the ATP-binding subunit. Invariably almost all of them display a common beta/alpha folding motif and have similar tertiary structures consisting of two globular domains. [Transport and binding proteins, Anions]

Substrate binding domain of ModA/WtpA from Pyrococcus furiosus and its closest homologs;the type 2 periplasmic binding protein fold; This subfamily contains domains found in ModA proteins that serve as initial receptors in the ABC transport of molybdate in eubacteria and archaea. Bacteria and archaea import molybdenum and tungsten from the environment in the form of the oxyanions molybdate (MoO(4) (2-)) and tungstate (WO(4) (2-)). After binding molybdate 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. In contrast to the structure of the two ModA homologs from Escherichia coli and Azotobacter vinelandii, where the oxygen atoms are tetrahedrally arranged around the metal center, the structure of Pyrococcus furiosus ModA/WtpA (PfModA) has shown that a binding site for molybdate and tungstate where the central metal atom is in a hexacoordinate configuration. The ModA 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.

molybdenum ABC transporter, periplasmic molybdate-binding protein; The model describes the molybdate ABC transporter periplasmic binding protein in bacteria and archae. Several of the periplasmic receptors constitute a diverse class of binding proteins that differ widely in size, sequence and ligand specificity. It has been shown experimentally by radioactive labeling that ModA represent hydrophylioc periplasmic-binding protein in gram-negative organisms and its counterpart in gram-positive organisms is a lipoprotein. The other components of the system include the ModB, an integral membrane protein and ModC the ATP-binding subunit. Invariably almost all of them display a common beta/alpha folding motif and have similar tertiary structures consisting of two globular domains. [Transport and binding proteins, Anions]

148-245 2.07e-04

Substrate binding domain of a putative iron transporter BitB, a member of the type 2 periplasmic binding fold superfamily; The substrate domain of this group shows a high homology to the periplasmic component of ferric iron transporter (Fbp), but its biochemical characterization has not been performed. 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. 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.
