K+-transporting ATPase


In enzymology, a K+-transporting ATPase is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are ATP, H2O, and K+, whereas its 3 products are ADP, phosphate, and K+.
This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides to catalyse transmembrane movement of substances. The systematic name of this enzyme class is ATP phosphohydrolase . Other names in common use include K+-translocating Kdp-ATPase, and multi-subunit K+-transport ATPase. This enzyme participates in two-component system - general.
