Mg2+-importing ATPase
In enzymology, a Mg2+-importing ATPase is an enzyme that catalyzes the chemical reaction
The 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 .
The mgtA gene which encodes this enzyme is thought to be regulated by a magnesium responsive RNA element.
