Comments [?]

case defined <Property:Membrane> and <Property:Membrane=2>
Function Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit binds the periplasmic potassium ions and delivers the ions to the membrane domain of KdpB through an intramembrane tunnel.

Function Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit binds the extracellular potassium ions and delivers the ions to the membrane domain of KdpB through an intramembrane tunnel.
end case
Subunit The system is composed of three essential subunits: KdpA, KdpB and KdpC.
case defined <Property:Membrane> and <Property:Membrane=2>
Subcellular location Cell inner membrane; Multi-pass membrane protein.
else
Subcellular location Cell membrane; Multi-pass membrane protein.
end case
Similarity Belongs to the KdpA family.
