Probably involved in copper and silver export. ATP + Cu(+)(in) + H2O = ADP + Cu(+)(out) + H(+) + phosphate Activated by Cu(+) and Ag(+) and inhibited by vanadate. Activated by CopZ in its Cu(+)-bound form. Shows higher affinity for Cu(+) compared with Ag(+). Optimum pH is 6.1-6.5. Optimum temperature is 75 degrees Celsius. Interacts with CopZ probably in the CopZ Cu(+)-bound form. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IB subfamily.
