The Cytochrome C-cytochrome Oxidase Complex
نویسنده
چکیده
In the preceding paper the oxidation of substrates by “indophenol oxidase” was demonstrated to be a joint action of cytochrome and cytochrome oxidase. It was further shown that with a given amount of oxidase the velocity of hydroquinone oxidation reached a maximum as the amount of added cytochrome was increased. The latter fact immediately suggested the probability that the rapid aerobic oxidation of reduced cytochrome C in the presence of the oxidase involved the formation of an enzymesubstrate complex (cytochrome oxidase-cytochrome C). In this paper we are presenting a study of the oxidation of hydroquinone by this complex and the influence of such factors as KCN, CO, and 02 upon the reaction.
