Copper + zinc and manganese superoxide dismutases inhibit deoxyribose degradation by the superoxide-driven Fenton reaction at two different stages. Implications for the redox states of copper and manganese.
When OH. radicals are formed in a superoxide-driven Fenton reaction, in which O2.- is generated enzymically, deoxyribose degradation is effectively inhibited by CuZn- and Mn-superoxide dismutases. The products of this reaction are H2O2 and a Fe3+-EDTA chelate. The mixing of H2O2 and a Fe3+-EDTA chel...
