-The '''cytochrome ''c''''' (cyt ''c'') proteins are a superfamily belonging to the class of [http://en.wikipedia.org/wiki/All-α_proteins all-α proteins], which are denoted as such by having an α-helical core. Each protein in this superfamily also contains one or more covalently-bound [http://en.wikipedia.org/wiki/Heme heme prosthetic groups].<ref>PMID:11697912</ref><ref name=main /> The cyt ''c'' superfamily contains many different families, some of which are better characterized than others. These families include monodomain and multi-domain C-type cytochromes, such as [http://proteopedia.org/wiki/index.php/1etp cyt c4], a diheme C-type cytochrome, and [http://proteopedia.org/wiki/index.php/2ozy NrfB], a pentaheme C-type cytochrome. In particular, the monoheme cyt ''c'' from ''Rhodothermus marinus'' has been previously studied and provides an excellent example of how some protein characteristics and structures can be extremely diverse, yet conserved, through evolution.<br />  For details on decaheme cyt see [[MtrF]].<br />  For details on Cyt c7 see [[Cytochrome c 7]].<br />
