Protein Domain : Tungstate ABC transporter, substrate-binding protein WtpA IPR022498

Type  Family
Description  Members of this protein family are tungstate (and, more weakly, molybdate) binding proteins of tungstate(/molybdate) ABC transporters, as first characterised in Pyrococcus furiosus. Note that this family is homologous to molybdate transporters, and that at least one other family of tungstate transporter binding protein, TupA, also exists. Bacterial high affinity transport systems are involved in active transport of solutes across the cytoplasmic membrane. Most of the bacterial ABC (ATP-binding cassette) importers are composed of one or two transmembrane permease proteins, one or two nucleotide-binding proteins and a highly specific periplasmic solute-binding protein. In Gram-negative bacteria the solute-binding proteins are dissolved in the periplasm, while in archaea and Gram-positive bacteria, their solute-binding proteins are membrane-anchored lipoproteins [ , ].
