- 論文の詳細を見る
Catalase catalyzed the peroxynitrite-mediated nitration of 4-hydroxyphenylacetic acid.The curve for the pH dependence of nitration was similar to that for the reaction between peroxynitrite and phenol.Cyanide, azide, and 3-amino-1, 2, 4-triazole inhibited the nitration in a dose-depen-dent way.When catalase was mixed with peroxynitrite, Compound I was detected as an intermediate.Because azide was an electron donor for the peroxidatic action of catalase, and because 3-amino-1, 2, 4-triazole inhibited catalase activity by binding with Compound I, peroxynitritemediated phenolic nitration was probably accompanied by Compound I formation.Both catalase and superoxide dismutase protected Escherichia coli from peroxynitrite toxicity.
