The mechanism of ubihydroquinone oxidation at the Qo-site of the cytochrome bc1 complex.

Biochimica et biophysica acta - 1 Jan 2000

Crofts Antony R, Hong Sangjin, Wilson Charles, Burton Rodney, Victoria Doreen, Harrison Chris, Schulten Klaus

Abstract excerpt

1. Recent results suggest that the major flux is carried by a monomeric function, not by an intermonomer electron flow. 2. The bifurcated reaction at the Qo-site involves sequential partial processes, - a rate limiting first electron transfer generating a semiquinone (SQ) intermediate, and a rapid second electron transfer in which the SQ is oxidized by the low potential chain. 3. The rate constant for the first...
