Abstract
Hydroperoxide-dependent naphthalene hydroxylation involving rat liver microsomes has been studied. The direct interaction between cytochrome p-450 and cumyl hydroperoxide (CHP) has been demonstrated. Km values with respect to both the substrate and CHP have been determined using intact and induced enzyme systems. The nature of the hydroxylating agent and the possible role of high-valence iron in the processes of hydroxylation by microsomal systems is discussed.
Abstract
Показано гидроксилилирование нафталина гидроперекисыо кумила ГПК. Показано непосредственное взаимодействие цитохрома P-450 с ГПК. Определены величины Km по субстрату и по ГПК при использовании интактных и индуцированных ферментных систем. Обсуждается природа гидроксилирующей частицы, а также возможная роль высших состояний железа в процессах гидроксилирования микросомальными системами.
