It is generally recognized that the multiplicity of cytochrome P450 forms in animals, especially those of the CYP2 family, is largely the result of the coevolution of plants and phytophageous animals. The rapidly advancing characterization of new cytochrome P450 enzymes in plants ( Durst 1991) shows that cytochromes P450 are …

WebJan 1, 2008 · Here we describe the biogenesis of cytochrome c that involves a post-translational protein modification, i.e. the covalent ligation of a heme prosthetic group. This pathway is different in plant and animal mitochondria, although c -type cytochromes fulfil similar functions in the respiratory chain. 2. WebCytochrome c is an ancient protein, developed early in the evolution of life. Since this essential protein performs a key step in the production of cellular energy, it has changed little in millions of years. So, you can look into yeast cells or plant cells or our own cells and find a very similar form of cytochrome c.
