Inenzymology, aMg2+-importing ATPase (EC3.6.3.2) is anenzyme thatcatalyzes thechemical reaction

ATP + H2O + Mg2+out{\displaystyle \rightleftharpoons } ADP + phosphate + Mg2+in

The 3substrates of this enzyme areATP,H2O, andMg2+, whereas its 3products areADP,phosphate, and Mg2+.

This enzyme belongs to the family ofhydrolases, specifically those acting on acid anhydrides to catalyse transmembrane movement of substances. Thesystematic name of this enzyme class isATP phosphohydrolase (Mg2+-importing).

ThemgtA gene which encodes this enzyme is thought to be regulated by amagnesium responsive RNA element.[1] A human enzyme was found inerythrocytes[2] but the observation could not be confirmed.
