CC -!- FUNCTION: Part of the high-affinity ATP-driven potassium transport (or
CC Kdp) system, which catalyzes the hydrolysis of ATP coupled with the
CC electrogenic transport of potassium into the cytoplasm. This subunit
CC binds the periplasmic potassium ions and delivers the ions to the
CC membrane domain of KdpB through an intramembrane tunnel.
CC {ECO:0000255|HAMAP-Rule:MF_00275}.
CC -!- SUBUNIT: The system is composed of three essential subunits: KdpA, KdpB
CC and KdpC. {ECO:0000255|HAMAP-Rule:MF_00275}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_00275}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_00275}.
CC -!- SIMILARITY: Belongs to the KdpA family. {ECO:0000255|HAMAP-
CC Rule:MF_00275}.
