Abstract

The effect of vanadium (V) on the activity of horseradish peroxidase, catalase, glutathione peroxidase, and superoxide dismutase has been studied. A competitive inhibition pattern was evident for vanadate ions on the activity of horseradish peroxidase (Ki = 41.2 μM). No significant inhibitory effects were found when V(V) was tested with catalase and when either V(IV) or V(V) were assayed with glutathione peroxidase. For the latter, the effect of V on the different components of the reaction system was investigated. V(V) did not significantly affect SOD activity when assayed with the sulfite method, which is devoid of interferences with V(V); however, there was an apparent inhibitory dose-response pattern for either V(IV) or V(V) using the pyrogallol assay, owing to an interference of pyrogallol with the metal. Besides, no significant binding of V(IV) or V(V) to the enzyme could be demonstrated. The lack of a direct inhibitory effect of V on the activity of the main antioxidant enzymes suggests that many biological and toxicological effects of V may be mediated more by oxidative reactions of the metal or of its complexes with physiologically relevant biomolecules than by a direct modulation of enzymatic activities.

      O2− and hydroperoxy radicals (HO2) have been shown to react directly with the membrane unsaturated fatty acids to result in LPO (Schaich, 1992). The studies of Serra et al. (1992) have demonstrated lack of a direct effect of vanadate and vanadyl on the activity of the main antioxidant enzymes (SOD and CAT), suggesting that many biological and toxicological effects of V may be mediated by oxidative reactions of the metal or of its complexes formed with physiologically relevant biomolecules, rather than by direct modulation of enzymatic activities. Therefore, a direct effect of SMV on SOD and CAT activity should be excluded.
