It must accept electrons from an electron donor, transfer the electrons between flavins, and transfer the electrons to an electron acceptor (e.g., cytochrome P450, cytochrome b 5, heme oxygenase, etc.) Additionally, the reductase must associate with …
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 WebThe first step is to transfer electrons via the Fe-S protein to Cytochrome c 1, which reduces cytochrome c. Secondly, the reduced coenzyme Q circulates electrons thru cytochrome c 1, cytochrome b L and intermediate oxidative states of coenzyme Q resulting in the regeneration of one reduced coenzyme Q, one more reduced cytochrome c, and the …
WebOct 28, 2024 · Cytochrome is used mainly by the mitochondria in the electron transport chain (ETC). The different cytochromes are in various places of the ETC, but each one has a basic role: transferring electrons.
