The Cytochrome C-cytochrome Oxidase Complex
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 oxidat...
متن کاملColorimetric microdetermination of cytochrome c oxidase.
The Nadi reaction, discovered by Ehrlich (1885), has been used for many years as a test for indophenol oxidase. The reaction consists in the formation of indophenol blue from dimethyl-p-phenylenediamine and cr-naphthol and is given by most animal and plant cells. It is now generally held that indophenol oxidase is identical with cytochrome c oxidase, and the Nadi reaction is often employed for ...
متن کاملSome agents which potentiate the inotropic response of the papillary muscle to epinephrine.
T HE CURRENT STUDY was suggested by the observation that various substances are capable of potentiating the inotropic response of the papillary muscle to epinephrine. The object of the study has been to obtain information about the nature of the action by which such substances as cysteine, cystine, tyrosine, ascorbic acid, and plasma are capable of producing this potentiation. Four possible sit...

متن کاملStudies on the Terminal Electron Transport System
The present communication is devoted to the description of the isolation, properties, and composition of a particulate unit which we shall refer to as the succinic dehydrogenase complex (SDC). The working hypothesis underlying this and subsequent communications in this series is that SDC is a unit of enzymatic action in the same sense as any well defined soluble enzyme. Since the discovery of s...
