Electron conduction between b cytochromes of the mitochondrial respiratory chain in the presence of antimycin plus myxothiazol. Biochimica et biophysica acta, 1988, Mar-30, Volume: 933, Issue:1 The b haems of the bc1 complex of bovine heart mitochondria were poised with succinate and fumarate so that only the high-potential haem (b-562) was reduced, and then isolated from further redox exchange with the ubiquinone pool by adding antimycin and myxothiazol. A transmembrane electric potential difference was then developed, either by electron flow from [Ru(NH3)6]Cl2 to oxygen or by ATP hydrolysis. The small difference spectrum, caused by the electric field, indicated 32-55% oxidation of b-562 with concomitant reduction of b-566. No lag greater than 0.1 s was detectable between the initiation of respiration and the development of the difference spectrum, thus providing a direct demonstration of (fairly) rapid electron transfer between the b haems.

The b haems of the bc1 complex of bovine heart mitochondria were poised with succinate and fumarate so that only the high-potential haem (b-562) was reduced, and then isolated from further redox exchange with the ubiquinone pool by adding antimycin and myxothiazol.

The small difference spectrum, caused by the electric field, indicated 32-55% oxidation of b-562 with concomitant reduction of b-566.
