CC   -!- FUNCTION: One of the components of the high-affinity ATP-driven
CC       potassium transport (or KDP) system, which catalyzes the
CC       hydrolysis of ATP coupled with the exchange of hydrogen and
CC       potassium ions. {ECO:0000255|HAMAP-Rule:MF_00285}.
CC   -!- CATALYTIC ACTIVITY: ATP + H(2)O + K(+)(Out) = ADP + phosphate +
CC       K(+)(In). {ECO:0000255|HAMAP-Rule:MF_00285}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00285}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00285}.
CC   -!- SIMILARITY: Belongs to the cation transport ATPase (P-type)
CC       (TC 3.A.3) family. Type IA subfamily. {ECO:0000255|HAMAP-
CC       Rule:MF_00285}.
