CC -!- FUNCTION: Part of the ABC transporter complex PtxABC involved in
CC phosphite import. Responsible for energy coupling to the transport
CC system (Probable). {ECO:0000305|PubMed:15231805,
CC ECO:0000305|PubMed:9791102}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + phosphite(out) = ADP + H(+) + phosphate +
CC phosphite(in); Xref=Rhea:RHEA:48972, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:36361,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216;
CC -!- SUBUNIT: The complex is composed of two ATP-binding proteins (PtxA),
CC two transmembrane proteins (PtxC) and a solute-binding protein (PtxB).
CC {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Peripheral
CC membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. Phosphonates
CC importer (TC 3.A.1.9.1) family. {ECO:0000305}.
