WebDec 24, 1996 · Peroxynitrite activates the cyclooxygenase activities of constitutive and inducible prostaglandin endoperoxide synthases by serving as a substrate for the enzymes’ peroxidase activities. Activation of purified enzyme is induced by direct addition of peroxynitrite or by in situgeneration of peroxynitrite from NO coupling to superoxide anion. WebFeb 20, 1999 · The activity of mammalian thioredoxin reductase as a peroxynitrite reductase was investigated. Peroxynitrite was infused to maintain a 0.2 μM steady-state concentration in potassium phosphate buffer (pH 7.4). Benzoate hydroxylation and nitrite formation were used as indices of oxidation reactions of peroxynitrite and of peroxynitrite reduction, … WebLe peroxynitrite induit l’oxydation et la nitration de molécules d’intérêt biologique les affectant dans leurs fonctions.
