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:0000255|HAMAP-Rule:MF_00276}.
CC   -!- SUBUNIT: The system is composed of three essential subunits: KdpA, KdpB
CC       and KdpC. {ECO:0000255|HAMAP-Rule:MF_00276}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00276}; Single-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00276}.
CC   -!- SIMILARITY: Belongs to the KdpC family. {ECO:0000255|HAMAP-
CC       Rule:MF_00276}.
