Domain Context

CATH Clusters

Superfamily Calcium-transporting ATPase, cytoplasmic domain N
Functional Family Magnesium-translocating P-type ATPase

Enzyme Information

7.2.2.14
P-type Mg(2+) transporter.
based on mapping to UniProt P0ABB8
ATP + H(2)O + Mg(2+)(Side 1) = ADP + phosphate + Mg(2+)(Side 2).
-!- A P-type ATPase that undergoes covalent phosphorylation during the transport cycle. -!- A bacterial enzyme that imports Mg(2+) with, rather than against, the Mg(2+) electrochemical gradient. -!- The enzyme is also involved in Ni(2+) import. -!- Formerly EC 3.6.3.2.
