Effect of chemicals on glutathione peroxidase of chick liver.
Chick liver glutathione peroxidase activity was separated into selenium-dependent and selenium-independent enzyme fractions and the effects of chemicals on the activities of each fraction were examined. Clofibrate induced the selenium-dependent enzyme, while phenobarbital, butylhydroxyanisole and trans-stilbene oxide elevated selenium-independent peroxidase activity. A third enzyme, which showed glutathione peroxidase activity toward both hydrogen peroxide and cumene hydroperoxide, was found.
