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 کاملThe reaction of the electrostatic cytochrome c-cytochrome oxidase complex with oxygen.
The reaction of the electrostatic cytochrome c-cytochrome oxidase complex with oxygen is measured by transient absorption spectroscopy. The oxygen reaction is initiated by photolytic removal of CO from cytochrome oxidase, using a flash-pumped dye laser. The subsequent reaction of the cytochrome c-cytochrome oxidase complex with oxygen is reported at 550, 605, 744, and 830 nm at different cytoch...
متن کاملA complex of cardiac cytochrome c1 and cytochrome c.
The interactions of cytochrome c1 and cytochrome c from bovine cardiac mitochondria were investigated. Cytochrome c1 and cytochrome c formed a 1:1 molecular complex in aqueous solutions of low ionic strength. The complex was stable to Sephadex G-75 chromatography. The formation and stability of the complex were independent of the oxidation state of the cytochrome components as far as those reac...
متن کاملThe Reaction of Cytochrome Oxidase with Cytochrome c*
In recent work on the reaction between oxygen and reduced cytochrome oxidase made by the method of Yonetani (1)) Gibson and Greenwood (2) found that the reaction is complex and that at least two spectroscopically distinguishable reactions must take place. The kinetic changes were interpreted in terms of a scheme proposed by Keilin and Hartree (3), according to which cytochrome oxidase preparati...
