Reaction: ATP + H2O + Mg2+out = ADP + phosphate + Mg2+in
Systematic name: ATP phosphohydrolase (Mg2+-importing)
Comments: A P-type ATPase that undergoes covalent phosphorylation during the transport cycle. This enzyme occurs in both Gram-positive and Gram-negative bacteria, and three types are known, designated as CorA, MgtA and MgtB. The CorA itself is not an ATPase but an Mg2+ transporter.
