Involved in copper export. Can also probably export ferric and lead ions. ATP + Cu(+)(in) + H2O = ADP + Cu(+)(out) + H(+) + phosphate Highest expression during the exponential growth phase. Induced by copper and, to some extent, by ferric and lead ions. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IB subfamily.
