6303331-1	1983	Through chemistry directly comparable to that of the hemocyanins and tyrosinase, half met-NO2- T2D laccase derivatives have been prepared; this NO2- reactivity entails both two electron oxidation of the cuprous binuclear site in deoxy T2D laccase and one electron reduction of the coupled cupric site in the met derivative.
