摘要

The peroxidases react with hydrogen peroxide to cleave the 0-0 bond and produce a protohemin derivative that is 2e-equiv more oxidized than the resting Fe (II1) p~ rphyrin.~,~ Recent evidence suggests that at least one of the electrons is removed from the porphyrin? r system to give a cation radical that is responsible for much of the electron transfer involved in substrate oxidation^.^^^
