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 type of heme and its mode of binding. Four varieties are recognized by the International Union … See more Cytochromes were initially described in 1884 by Charles Alexander MacMunn as respiratory pigments (myohematin or histohematin). In the 1920s, Keilin rediscovered these respiratory pigments and named them … See more The heme group is a highly conjugated ring system (which allows its electrons to be very mobile) surrounding an iron ion. The iron in cytochromes usually exists in a ferrous (Fe ) and a … See more • Scripps Database of Metalloproteins • Cytochromes at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more WebAug 8, 2024 · Cytochromes are the proteins with characteristic absorption of visible lights due to the presence of heme containing Fe as co-factor. There are three different types of cytochrome a, b and c. Cytochrome a and b are tightly but not covalently linked with their proteins whereas cytochrome c is covalently bonded with its protein through cysteine.
