Comments [?]

Function Part of the ABC transporter complex PstSACB involved in phosphate import. Responsible for energy coupling to the transport system.
Catalytic activity RHEA:24440: ATP + H2O + phosphate(out) = ADP + H(+) + 2 phosphate(in)
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.
