Iron-chelate-transporting ATPase

In enzymology, an iron-chelate-transporting ATPase is an enzyme that catalyzes the chemical reaction


 * ATP + H2O + iron chelateout $$\rightleftharpoons$$ ADP + phosphate + iron chelatein

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

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 (iron-chelate-importing). This enzyme participates in abc transporters - general.
