Abstract
Peterson and Eaton (1989, Biochem. Biophys. Res. Commun. 165, 164-167) reported that the copper- and zinc-containing, but not the manganese-containing, superoxide dismutase catalyzes the reduction of cytochrome c by ferrous salts. This activity, erroneously attributed to the enzyme, is now shown to have been due to inorganic phosphate.
