Cytochrome - Wikipedia
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 … 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. The iron in cytochromes usually exists in a ferrous (Fe ) and a ferric (Fe ) state with a ferroxo (Fe ) state found in catalytic intermediates. … See more WebComponents of the Electron Transport Chain. When electrons flow down the energy gradient from NADH to O2, the four protein complexes that catalyze the redox reaction are: Complex I = NADH-Q reductase complex. Complex III= Cytochrome c reductase complex. Cyt C = Cytochrome c. Complex IV = Cytochrome c oxidase complex. dwer annual environmental report
