The annotation and conditions in this rule are derived from the following entries: P03961 (KDPC_ECOLI)

If a protein meets these conditions... i

Common conditions

Special conditions

    • proteome property = Membrane=2
    • proteome property ≠ Membrane=*
    • proteome property ≠ Membrane=2
    • Predicted transmembrane

... then these annotations are applied i

Protein namei

  • Recommended name:
    Potassium-transporting ATPase KdpC subunit
    Alternative name(s):
    Potassium-translocating ATPase C chain
    ATP phosphohydrolase [potassium-transporting] C chain
    Potassium-binding and translocating subunit C

Gene namei

  • Name:kdpC

Sequence similaritiesi

Functioni

  • 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 acts as a catalytic chaperone that increases the ATP-binding affinity of the ATP-hydrolyzing subunit KdpB by the formation of a transient KdpB/KdpC/ATP ternary complex.

Subunit structurei

  • The system is composed of three essential subunits: KdpA, KdpB and KdpC.

Subcellular locationi

Transmembranei

  • Helical (to residues corresponding to positions @FROM@i - @TO@i)
