WebThe redox properties of cytochromes (cyt) c, a ubiquitous class of heme-containing electron transport proteins, have been extensively investigated over the last two decades. The reduction potential (E degrees') is central to the chemistry of cyt c for two main reasons. Weboxidized cytochrome c which reduces it to Fe2+. Cytochrome c then releases the electron to Complex IV. The iron center then returns to the Fe3+ oxidized state. Even though the …
