The interaction of bovine erythrocyte superoxide dismutase with hydrogen peroxide: inactivation of the enzyme

Biochemistry

Dec 2, 1975

E K Hodgson, Irwin Fridovich

Abstract

Bovine erythrocyte superoxide dismutase was slowly and irreversibly inactivated by hydrogen peroxide. The rate of this inactivation was directly dependent upon the concentrations of both H2O2 and of enzyme, and its second-order rate constant at pH 10.0 and 25 degrees was 6.7 M-1 sec-1. ...read more
