kdpC1

Gene
kdpC1
Protein
Potassium-transporting ATPase KdpC subunit 1
Organism
Nostoc sp. (strain PCC 7120 / SAG 25.82 / UTEX 2576)
Length
202 amino acids
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 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.
Similarity
Belongs to the KdpC family.
