| Abstract: | There are now four structures of vertebrate mitochondrial bc1 complexes available in theprotein databases and structures from yeast and bacterial sources are expected soon. Thisreview summarizes the new information with emphasis on the avian cytochrome bc1 complex(PDB entries 1BCC and 3BCC). The Rieske iron–sulfur protein is mobile and this has beenproposed to be important for catalysis. The binding sites for quinone have been located basedon structures containing inhibitors and, in the case of the quinone reduction site Qi, thequinone itself. |
