IntEnz Enzyme Nomenclature
EC 3.6.3.54

Names

Accepted name:
Cu+ exporting ATPase
Other names:
CopA
ATP7A
ATP7B
Systematic name:
ATP phosphohydrolase (Cu+-exporting)

Reaction

Comments:

A P-type ATPase that undergoes covalent phosphorylation during the transport cycle. This enzyme transports Cu+ or Ag+, and cannot tranport the divalent ions, contrary to EC 3.6.3.4, Cu2+-exporting ATPase, which mainly transports the divalent copper ion.
