Inactivation of erythrocyte GSH-peroxidase correlates with the rate of hemoglobin oxidation. The presence of superoxide dismutase and catalase only marginally reduces the rate of inactivation of the enzyme indicating that the loss of activity is not due to oxygen radicals produced during oxidation of hemoglobin. The inactivation of glutathione peroxidase is due by-and-large to the formation of hemichromes.

Abstract
Inactivation of erythrocyte GSH-peroxidase correlates with the rate of hemoglobin oxidation. The presence of superoxide dismutase and catalase only marginally reduces the rate of inactivation of the enzyme indicating that the loss of activity is not due to oxygen radicals produced during oxidation of hemoglobin. The inactivation of glutathione peroxidase is due by-and-large to the formation of hemichromes.File in questo prodotto:
