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 acts as a catalytic chaperone that increases the ATP-binding affinity
CC of the ATP-hydrolyzing subunit KdpB by the formation of a transient
CC KdpB/KdpC/ATP ternary complex. {ECO:0000256|HAMAP-Rule:MF_00276}.
CC -!- SUBUNIT: The system is composed of three essential subunits: KdpA, KdpB
CC and KdpC. {ECO:0000256|HAMAP-Rule:MF_00276}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_00276};
CC Single-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00276}.
CC -!- SIMILARITY: Belongs to the KdpC family. {ECO:0000256|HAMAP-
CC Rule:MF_00276}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
