Cytochromes are, thus, capable of performing electron transfer reactions and catalysis by reduction or oxidation of their heme iron. The cellular location of cytochromes depends on their function. They can be found as globular proteins and membrane proteins . See more Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis. They are classified according to the … See more Cytochromes were initially described in 1884 by Charles Alexander MacMunn as respiratory pigments (myohematin or histohematin). In the 1920s, Keilin rediscovered these … See more • Scripps Database of Metalloproteins • Cytochromes at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more The heme group is a highly conjugated ring system (which allows its electrons to be very mobile) surrounding an iron ion.

WebCytochrome P450 monooxygenases catalyze the oxidation and metabolism of a large number of xenobiotics and endogenous compounds. CYP450 enzymes evolved as the primary defense against xenobiotics and in this process are also responsible for the bioactivation of drugs and toxicants to more reactive intermediates.
