Sulfate-transporting ATPase

From Wikipedia, the free encyclopedia

In enzymology, a sulfate-transporting ATPase (EC 3.6.3.25) is an enzyme that catalyzes the chemical reaction

ATP + H₂O + sulfateout $\rightleftharpoons$ ADP + phosphate + sulfatein

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

This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides acting on acid anhydrides to catalyse transmembrane movement of substances. The systematic name of this enzyme class is ATP phosphohydrolase (sulfate-importing). This enzyme participates in abc transporters - general.
