NamePotassium-transporting ATPase KdpFABC
DescriptionThe Kdp complex is a high affinity P-type ATPase potassium ion transport system, found widely distributed among prokaryotes. Regulated by increases in osmolarity and/or reduction in external potassium, Kdp is the only K+ transport system whose expression is regulated by environmental conditions [1]. Kdp is composed of four membrane-bound subunits responsible for potassium ion binding and transport, ATP hydrolysis, and complex assembly and stability [2]. Not defined by this property are the sensor kinase and response regulator components, which once stimulated by specific environmental signals, induce expression of the adjacent Kdp gene cluster [1,2].
