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:0000256|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 ChEBI:CHEBI:456216; EC=7.2.2.6; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00285};
CC -!- SUBUNIT: The system is composed of three essential subunits: KdpA, KdpB
CC and KdpC. {ECO:0000256|HAMAP-Rule:MF_00285}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_00285};
CC Multi-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00285}.
CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC family. Type IA subfamily. {ECO:0000256|HAMAP-Rule:MF_00285}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
