Cytochromes c in chloroplasts, Gram-positive bacteria, cyanobacteria, and some Pseudomonadota are produced by the cytochrome c synthesis (ccs) system. It is composed of two membrane proteins CcsB and CcsA. WebTwo kinds of cytochromes C, cytochromes c550 and c551 are obtained from T. novellus and have been well characterized. Cytochrome c (550, T. novellus) is rather similar to the mammalian-type cytochrome c in spite of its bacterial origin ( Yamanaka, 1972a, b). Although its isoelectric point exists at pH 7.5, it has thirteen lysine residues in one ...

WebMar 1, 1987 · Abstract Several heme aa3 -type cytochrome c oxidases, purified from the cytoplasmic membranes of bacteria, are able to catalyze the same reactions as the structurally far more complex eukaryotic enzyme, i.e., electron transport from cytochrome c to oxygen coupled to proton translocation. The attachment of the heme group is physically separated from the protein biosynthesis. Proteins are synthesized within the cytoplasm and endoplasmic reticulum, while the maturation of cytochromes c occurs in the periplasm of prokaryots, the intermembrane space of mitochondria or the stroma of chloroplasts. Several biochemical pathways have been discovered that differ depending on organism. greater than function
