Structure and function of the isolated complex

Cyt b-c complex forms the evolutionary link betw.een the respiratory and photosynthetic electron-transport pathways [3]. In both systems it oxidizes quinols and reduces metalloproteins while generating protonmotive force. In cyanobacteria, the Cyt /jg-/complex is shared by both respiration and photosynthesis [21].
