FUNCTION: Part of the ABC transporter complex PotABCD involved in spermidine/putrescine import. Responsible for energy coupling to the transport system (By similarity).
CATALYTIC ACTIVITY: ATP + H(2)O + polyamine(Out) = ADP + phosphate + polyamine(In).
SUBUNIT: The complex is composed of two ATP-binding proteins (PotA), two transmembrane proteins (PotB and PotC) and a solute-binding protein (PotD) (Potential).
case not defined <Property:Membrane> or <Property:Membrane=1>
SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein (By similarity).
else case <Property:Membrane=2>
SUBCELLULAR LOCATION: Cell inner membrane; Peripheral membrane protein (By similarity).
end case
SIMILARITY: Belongs to the ABC transporter superfamily. Spermidine/putrescine importer (TC 3.A.1.11.1) family.
