Effect of Superoxide and Superoxide Dismutase on Lignin Peroxidase-Catalyzed Veratryl Alcohol Oxidation

We have shown that superoxide (O⨪2) is produced during the oxidation of veratryl alcohol by lignin peroxidase (LiP) by the reaction of the veratryl alcohol cation radical with hydrogen peroxide (D. B. Barr, M. M. Shah, and S. D. Aust, 1993, J. Biol. Chem. 268, 241-244). Compound III, an inactive for...
