Members of this class are e.g. cytochrome c 7 (triheme), cytochrome c 3 (tetraheme), and high-molecular-weight cytochrome c (Hmc), containing 16 heme groups with only 30-40 residues per heme group. The 3D structures of a number of cyt c 3 proteins have been determined. See more Cytochromes c (cyt c, c-type cytochromes) cytochromes, or heme-containing proteins, that have heme C covalently attached to the peptide backbone via one or two thioether bonds. These bonds are in most cases part of a specific See more Cytochrome c proteins can be divided in four classes based on their size, number of heme groups and reduction potentials: Class I See more CYCS; CYC1 See more The attachment of the heme group is physically separated from the protein biosynthesis.
