Electron and Proton Transfer in The Cytochrome bf Complex
The Q-cycle has adequately accounted for many features of electron and proton transfers through the be complexes. A number of experimental observations have, however, offered challenges to this as a full explanation for the behaviour of the cytochrome bf complex. in this and the accompanying manuscript, we investigate these anomalies further, both in the isolated complex and in thylakoids, and attempt to present a working hypothesis within the Q-cycle framework which can accomodate these data.
