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 کاملStudies on cytochrome oxidase. IV. The cytochrome oxidase activity.
where the activity is determined by measuring the rate of oxidation of reduced cytochrome c. Smith (6, 7), Conrad (8, 9), Wainio (10-13) et ~2. have extensively investigated the effect of various factors on the cytochrome oxidase activity measured by System 2 with soluble and insoluble preparations of cytochrome oxidase, whereas among those (14-30) who have employed System 1, Slater (5), using ...
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 کاملCytochrome c oxidase.
Within the past year, the structures of the cytochrome c oxidase from the soil bacterium Paracoccus denitrificans and of the metal centers of the cytochrome c oxidase from bovine heart mitochondria, both determined at 2.8 A resolution by X-ray crystallography, have been reported. The structures form a basis for understanding the mechanism of this redox-coupled transmembrane proton pump, which i...
متن کاملPeroxidase and cytochrome oxidase in rat tissues.
The presence of peroxidase in the uterus of the estrogeninjected ovariectomized rat and in the Walker carcinosarcoma No. 256 of rats has been reported previously (1, 2). In view of the fact that both these tissues undergo rapid proliferation, it was thought of interest to survey several other rat tissues to determine whether peroxidase might be generally associated with proliferation. Bancroft ...
