In enzymology, a chloroplast protein-transporting ATPase (EC 3.6.3.52) is an enzyme that catalyzes the chemical reaction
- ATP + H2O [math]\displaystyle{ \rightleftharpoons }[/math] ADP + phosphate
Thus, the two substrates of this enzyme are ATP and H2O, 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 (chloroplast protein-importing).
