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 is
CC       responsible for energy coupling to the transport system and for the
CC       release of the potassium ions to the cytoplasm. {ECO:0000255|HAMAP-
CC       Rule:MF_00285}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O + K(+)(out) = ADP + H(+) + K(+)(in) + phosphate;
CC         Xref=Rhea:RHEA:16777, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:29103, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474,

CC         Rule:MF_00285};
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:16778;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00285};
CC   -!- SUBUNIT: The system is composed of three essential subunits: KdpA, KdpB
CC       and KdpC. {ECO:0000255|HAMAP-Rule:MF_00285}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00285};
CC       Multi-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00285}.
CC   -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC       family. Type IA subfamily. {ECO:0000255|HAMAP-Rule:MF_00285}.
