The 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...

متن کاملThe 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 cytochrome c binding site on cytochrome c oxidase.
Cytochrome c oxidase (EC 1.9.3.1) is the terminal enzyme of the mitochondria respiratory chain catalysing electron transfer from cytochrome c to molecular oxygen [ 1,2]. The molecular mechanism of this process is still not understood. At present, little is known about such important structural features as the position of the prosthetic groups or the location and characteristics of the cytochrom...
متن کاملKinetic studies on the reaction between cytochrome c oxidase and ferrocytochrome c.
In stopped-flow experiments in which oxidized cytochrome c oxidase was mixed with ferrocytochrome c in the presence of a range of oxygen concentrations and in the absence and presence of cyanide, a fast phase, reflecting a rapid approach to an equilibrium, was observed. Within this phase, one or two molecules of ferrocytochrome were oxidized per haem group of cytochrome a, depending on the conc...
