Reduction and activity of cytochrome c in the cytochrome c-cytochrome aa3 complex.
Uncharged reductants, such as NNN'N'-tetramethyl-p-phenylenediamine and diaminodurene, reduce cytochrome c at both high and low ionic strength, unlike ascorbate, which is effective only at low ionic strength. The 'tightly bound' cytochrome c-cytochrome c oxidase complex, with 1 equiv. of cytochrome c per cytochrome aa3, can be prepared by simple mixing of the two component species. Its properti...
متن کاملMultiwavelength analysis of the kinetics of reduction of cytochrome aa3 by cytochrome c.
Some new approaches to the kinetic study of the reduction of cytochrome aa3 by cytochrome c are presented. The primary innovations are the use of a spectrometer which can acquire multiwavelength data as fast as every 10 microseconds, and the application of a variety of analytical methods which can utilize simultaneously all of the time-resolved spectral data. These techniques include singular v...
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-cyanide complex.
In the course of studies involving the reduction of ferricytochrome c by the succinic dehydrogenase system, it was observed that in the presence of cyanide there is a progressive decrease in the amount of reducible eytochrome c. This action of cyanide on cytochrome c had previously been reported by Pott.er (l), together with other evidence indicating the formation of a ferricytochrome c-cyanide...
