In enzymology a Mg2+-importing ATPase (EC 3.6.3.2) is an enzyme that catalyzes the chemical reactionATP + H2O + Mg2+out ADP + phosphate + Mg2+inThe 3 substrates of this enzyme are ATP H2O and Mg2+ whereas its 3 products are ADP phosphate and Mg2+.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 (Mg2+-importing).
