kdpA

FUNCTION: One of the components of the high-affinity ATP-driven potassium transport (or KDP) system, which catalyzes the hydrolysis of ATP coupled with the exchange of hydrogen and potassium ions (By similarity).

CATALYTIC ACTIVITY: ATP + H(2)O + K(+)(Out) = ADP + phosphate + K(+)(In).

SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein (By similarity).

SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein (By similarity).

SIMILARITY: Belongs to the KdpA family.
