CC   -!- FUNCTION: Part of the ABC transporter complex PotABCD involved in
CC       spermidine/putrescine import. Responsible for energy coupling to the
CC       transport system. {ECO:0000255|HAMAP-Rule:MF_01726}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O + polyamine-[polyamine-binding protein]Side 1 = ADP
CC         + phosphate + polyamineSide 2 + [polyamine-binding protein]Side 1.;
CC         EC=7.6.2.11; Evidence={ECO:0000255|HAMAP-Rule:MF_01726};
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (PotA),
CC       two transmembrane proteins (PotB and PotC) and a solute-binding protein
CC       (PotD). {ECO:0000255|HAMAP-Rule:MF_01726}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01726}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01726}.
CC   -!- SIMILARITY: Belongs to the ABC transporter superfamily.
CC       Spermidine/putrescine importer (TC 3.A.1.11.1) family.
CC       {ECO:0000255|HAMAP-Rule:MF_01726}.
