WebCytochrome c is a highly conserved ~12 kDa protein consisting of a single 104 amino acid peptide with a single heme group, which is covalently attached to Cys 14 and Cys 17. Because of its ubiquitous nature and sequence homology, cytochrome c has been used as a model protein for molecular evolution. 1. Webcytochrome, any of a group of hemoprotein cell components that, by readily undergoing reduction and oxidation (gain and loss of electrons) with the aid of enzymes, serve a vital …
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 the cytochromes, or “cellular pigments”. He classified these heme proteins on the basis of the position of … 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 The heme group is a highly conjugated ring system (which allows its electrons to be very mobile) surrounding an iron ion.
