Effect of ubiquinone extraction on ubiquinol-1 oxidase activity in beef heart mitochondria.

P Pasquali, L Landi, L Cabrini, G Lenaz.   

Abstract

Extraction of endogenous ubiquinone with different methods does not influence ubiquinol oxidase activity in lyophilized mitochondria in terms of KM, although a decrease of Vmax is sometimes observed. Experiments with submitochondrial particles from a UQ-deficient mutant of S. cerevisiae confirm the results with UQ-depleted mitochondria and support the idea that endogenous ubiquinone is not required for the oxidation of exogenous ubiquinols by complex III.
