title: Reactions of radiolytically-generated superoxide anion with higher oxidation states of lactoperoxidase.
abstract: The time-courses of absorption changes after pulse radiolysis of oxygen-saturated solution of lactoperoxidase have been studied. Radiation-generated superoxide reduces compounds I to II. The results suggest that superoxide anion reacts also with compound II of lactoperoxidase; however, the reduction of the heme iron has not been observed. A possible reaction pathway of compound II in the presence of superoxide anion is discussed.
