| Short Name | KdpA |
| description | Kdp is a high affinity ATP-driven K+ transport system in Escherichia coli. It is a membrane complex (KdpFABC) composed of four subunits, KdpA, KdpB, KdpC and KdpF, although KdpF is not present in some species []. It maintains intracellular homeostasis, cell shape and turgor under potassium-limiting conditions. KdpA is the K+-transporting subunit of this complex, while KdpB is a P-type ATPase that provides the energy for K+ transport. Both subunits are joined by KdpC, a probable catalytic chaperone and KdpF, that may stabilize the complex. KdpC and KdpF have single transmembrane helices and no known homologues outside of Kdp [, ].This family represents the KdpA subunit of KdpFABC complex. |
