WebCytochromes 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. The CcsBA protein complex was suggested to act as a heme transporter during the attachment process. [20] WebCytochrome P450 enzymes are primarily found in liver cells but are also located in cells throughout the body. While a large body of knowledge exists on the role of CYP450s in xenobiotic metabolism, recent studies have begun to reveal the endogenous functions carried out by this important superfamily of enzymes.
