The complete amino acid sequence of chicken heart cytochrome c has been established. This primary structure is typically that of a "mammalian-type" cytochrome c showing the characteristic groupings of hydrophobic and basic residues, and, like the other cytochromes c from vertebrate species, has an acetylated amino-terminal residue. Chicken heart cytochrome c differs from the horse, beef, human, pig, tuna, moth, and bakers' yeast iso-1-cytochrome c proteins by 11, 9, 12, 9, 19, 28, and 45 residues, respectively.
