Copper chaperone CopZ, as the name is used in Enterococcus hirae and related species, is a small copper-binding protein with close homology to domains found, sometimes in multiple copies, in various copper-translocating copper-translocating P-type ATPases, and to distinct families of other small copper chaperones that also named CopZ.
