EC 7.2.2.9

Reaction: ATP + H₂O + Cu²⁺_{[side 1]} = ADP + phosphate + Cu²⁺_{[side 2]}

Other name(s): Cu²⁺-exporting ATPase; copB (gene name)

Systematic name: ATP phosphohydrolase (P-type, Cu²⁺-exporting)

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