Les cytochromes P450 des vertébrés sont principalement exprimés dans le foie. Les composés qu'ils oxydent deviennent plus polaires et peuvent être ainsi excrétés, en particulier par les reins, dans les urines. WebThe role cytochrome c oxidase plays is to remove electrons from the chain by transferring them to O 2 with H + to produce water. In aerobic bacterial species that do not have cytochrome c oxidase, this process still occurs, but using an enzyme that has a different structure and different name than cytochrome c oxidase.

WebCytochrome c is a small, water-soluble protein of molecular weight about 12,000. It is a peripheral membrane protein since it can be readily stripped (without detergent) from mitochondrial membranes where it is found. Cytochrome c is associated with specific binding sites on integral membrane proteins extending from the membrane surface.
