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}.
