II. Sequence determination of the entire RT genome and assignment of potential protein-coding regions."; RL DNA Res. 3:109-136(1996). 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}.
