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       binds the periplasmic potassium ions and delivers the ions to the
CC       membrane domain of KdpB through an intramembrane tunnel.

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       binds the extracellular potassium ions and delivers the ions to the
CC       membrane domain of KdpB through an intramembrane tunnel.
end case
CC   -!- SUBUNIT: The system is composed of three essential subunits: KdpA, KdpB
CC       and KdpC.
case defined <Property:Membrane> and <Property:Membrane=2>
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein.
else
CC   -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
end case
CC   -!- SIMILARITY: Belongs to the KdpA family.
