Genes for cytochrome c and cytochrome c oxidase synthesis in Bacillus subtilis
Cytochromes are heme-containing proteins that function in electron transfer reactions, e.g. respiration and photosynthesis. There are several different types of cytochromes. C-type cytochromes differ from other types of cytochromes in that the heme group is covalently attached to the polypeptide via thioether bonds to two cysteinyl residues in a consensus motif, Cys-Xaa-Yaa-Cys-His. Cytochrome c o
