FUNCTION	Part of the ABC transporter complex PstSACB involved in phosphate import. Responsible for energy coupling to the transport system.
CATALYTIC ACTIVITY	Reaction=ATP + H2O + phosphate(out) = ADP + H(+) + 2 phosphate(in); Xref=Rhea:RHEA:24440, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=7.3.2.1;
SUBUNIT	The complex is composed of two ATP-binding proteins (PstB), two transmembrane proteins (PstC and PstA) and a solute-binding protein (PstS).
case not defined <Property:Membrane> or <Property:Membrane=1>
SUBCELLULAR LOCATION	Cell membrane; Peripheral membrane protein.
else case <Property:Membrane=2>
SUBCELLULAR LOCATION	Cell inner membrane; Peripheral membrane protein.
end case
SIMILARITY	Belongs to the ABC transporter superfamily. Phosphate importer (TC 3.A.1.7) family.
