Abstract
A novel superoxide dismutase prepared from a superoxide dismutase-producing strain of the genus Nocardiopsis. The enzyme is a tetramer with a molecular weight of about 8.8.times.10.sup.4, composed of sub-units of about 2.2.times.10.sup.4. The superoxide dismutase contains 1.56 g-atoms of iron per mole but no copper or manganese. Potassium cyanide at a concentration of 1 mM does not inhibit activity, however exponential inactivation is caused by 5 mM hydrogen peroxide.
