A perspective on Q-cycles
Abstract
An examination is made of both the Q-cycle and b-cycle formulations of electron transfer and energy conservation in the cytochrome bc1 complex. A working hypothesis for the complex is presented, based upon the Q-cycle notion of vectorial reaction sites, but incorporating the b-cycle feature of semiquinone movement between these sites.
