DESCRIPTION

Also known as KDPF_ECOLI, kdpF. 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 (PubMed:23930894). This subunit may be involved in stabilization of the complex (PubMed:10608856). The system is composed of three essential subunits: KdpA, KdpB and KdpC (PubMed:10608856, PubMed:28636601, PubMed:30478378). The complex also contains KdpF, a small non-essential subunit (PubMed:10608856, PubMed:28636601, PubMed:30478378). The KdpFABC complex exists as a dimer above concentrations of 30-50 nM, whereas the complex exists as a functional monomer at lower concentrations (PubMed:18298081).
