Figure 3 Structure of the intermembrane (external surface) domains of the chicken bc[1] complex. This is viewed from within the membrane, with the transmembrane helices truncated at roughly the membrane surface. Ball-and-stick models represent the haem group of cytochrome c[1], the Rieske iron-sulphur cluster, and the disulphide cysteines of subunit 8. SU, subunit; cyt, cytochrome.
