Phosphate-transporting ATPase

In enzymology, a phosphate-transporting ATPase is an enzyme that catalyzes the chemical reaction


 * ATP + H2O + phosphate(out) $$\rightleftharpoons$$ ADP + phosphate + phosphate(in)

The 3 substrates of this enzyme are ATP, H2O, and phosphate, whereas its two products are ADP and phosphate.

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 (phosphate-importing). This enzyme is also called ABC phosphate transporter. This enzyme participates in abc transporters - general.
