CC   -!- FUNCTION: Part of the ABC transporter complex PstSACB involved in
CC       phosphate import. {ECO:0000250}.
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:0000305}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the PstS family. {ECO:0000305}.
