CC   -!- FUNCTION: Part of the high-affinity ATP-driven potassium transport
CC       (or Kdp) system, which catalyzes the hydrolysis of ATP coupled
CC       with the electrogenic transport of potassium into the cytoplasm.
CC       This subunit is responsible for energy coupling to the transport
CC       system. {ECO:0000255|HAMAP-Rule:MF_00285}.
CC   -!- CATALYTIC ACTIVITY: ATP + H(2)O + K(+)(Out) = ADP + phosphate +
CC       K(+)(In). {ECO:0000255|HAMAP-Rule:MF_00285}.
CC   -!- SUBUNIT: The system is composed of three essential subunits: KdpA,
CC       KdpB and KdpC. {ECO:0000255|HAMAP-Rule:MF_00285}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00285}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00285}.
CC   -!- SIMILARITY: Belongs to the cation transport ATPase (P-type)
CC       (TC 3.A.3) family. Type IA subfamily. {ECO:0000255|HAMAP-
CC       Rule:MF_00285}.
