Which of the following enzymes does NOT contain Cu2+?: (A) Ceruloplasmin, (B) Cytochrome Oxidase, (C) Xanthine oxidase, (D) Superoxide Dismutase
Answer is C. Dopamine hydroxylase Peptidylglycine hydroxylase, Ceruloplasmin(copper containg plasma protein, enzyme) Amine oxidase Copper-dependent superoxide dismutase Cytochrome oxidase Tyrosinase lysyl oxidase Hephaestin, ferroxidase Ascorbic acid has specific roles in the copper-containing hydroxylases and the -ketoglutarate-linked iron-containing hydroxylases Superoxide diamutase is Zn containing
