Anti-cooperative oxidation of ubiquinol by the yeast cytochrome bc1 complex.

The Journal of biological chemistry - 9 Apr 2004

Covian Raul, Gutierrez-Cirlos Emma Berta, Trumpower Bernard L

Abstract excerpt

We have investigated the interaction between monomers of the dimeric yeast cytochrome bc(1) complex by analyzing the pre-steady and steady state activities of the isolated enzyme in the presence of antimycin under conditions that allow the first turnover of ubiquinol oxidation to be observable in cytochrome c(1) reduction. At pH 8.8, where the redox potential of the iron-sulfur protein is approximately 200 mV and...
