Involved in copper export. Could be involved in the copper detoxification of mycobacterial cells. ATP + Cu(+)(in) + H2O = ADP + Cu(+)(out) + H(+) + phosphate ATPase activity is stimulated by Cu(+) ions. Optimum pH is 7.5. Optimum temperature is 37 degrees Celsius. Active across a broad temperature range. Up-regulated in pulmonary and extrapulmonary TB patients. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IB subfamily.
