“Type-2 Cu sites are found in all the major branches of life and are often involved in the catalysis of oxygen species. Four type-2 Cu protein families are selected as model systems for review: amine oxidases, Cu monooxygenases, nitrite reductase/multicopper oxidase, and CuZn superoxide dismutase.”
