IntEnz Enzyme Nomenclature
EC 3.6.3.2

Names

Accepted name:
Mg2+-importing ATPase
Systematic name:
ATP phosphohydrolase (Mg2+-importing)

Reaction

Cofactor

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.
