IntEnz Enzyme Nomenclature


Accepted name:
P-type Cu2+ transporter
Other names:
Cu2+-exporting ATPase
Systematic name:
ATP phosphohydrolase (P-type, Cu2+-exporting)




A P-type ATPase that undergoes covalent phosphorylation during the transport cycle. The enzyme from the termophilic bacterium Archaeoglobus fulgidus is involved in copper extrusion from the cell [1,2].
