Conformationally linked interaction in the cytochrome bc(1) complex between inhibitors of the Q(o) site and the Rieske iron-sulfur protein.

Biochimica et biophysica acta - 1 Oct 2011

Berry Edward A, Huang Li-Shar

Abstract excerpt

The modified Q cycle mechanism accounts for the proton and charge translocation stoichiometry of the bc(1) complex, and is now widely accepted. However the mechanism by which the requisite bifurcation of electron flow at the Q(o) site reaction is enforced is not clear. One of several proposals involves conformational gating of the docking of the Rieske ISP at the Q(o) site, controlled by the stage of the reaction...
