CC   -!- FUNCTION: Part of the ABC transporter complex PstSACB involved in
CC       phosphate import. Responsible for energy coupling to the transport
CC       system. {ECO:0000255|HAMAP-Rule:MF_01702}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O + phosphate(out) = ADP + H(+) + 2 phosphate(in);
CC         Xref=Rhea:RHEA:24440, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=7.3.2.1;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01702};
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (PstB),
CC       two transmembrane proteins (PstC and PstA) and a solute-binding protein
CC       (PstS). {ECO:0000255|HAMAP-Rule:MF_01702}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01702}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01702}.
CC   -!- SIMILARITY: Belongs to the ABC transporter superfamily. Phosphate
CC       importer (TC 3.A.1.7) family. {ECO:0000255|HAMAP-Rule:MF_01702}.
