Necessary for copper homeostasis and likely functions as a copper exporter. Also required for full virulence. ATP + Cu(+)(in) + H2O = ADP + Cu(+)(out) + H(+) + phosphate Induced by copper ions via CsoR. Mutants show increased copper sensitivity. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IB subfamily.
