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 and transports the potassium across the cytoplasmic membrane (By similarity). The Kdp system is essential for growth under K(+) limitation, and for survival under desiccation and salt crystal inclusion (PubMed:18633573, PubMed:23757278).

Belongs to the KdpA family.
