CONTRASTING ROUTES OF C-TYPE CYTOCHROME ASSEMBLY IN MITOCHONDRIA, CHLOROPLASTS AND BACTERIA

The biogenesis of bacterial c-type cytochromes generally involves many gene products - some of which may also have roles in other processes - and their interaction with the disulphide-bond-forming system of the bacterial periplasm. However, in some bacteria a simpler process appe ars to operate that might be related to the formation of c-type cytoch romes in thylakoids of photosynthetic cells. The corresponding process in fungal mitochondria is distinct.
