Common NameFerrocytochrome
DescriptionFerricytochrome is a cytochrome containing reduced (ferrous) iron. Cytochrome c is an electron-carrying protein found in mitochondria of all aerobic organisms. It is part of the terminal oxidation chain, which completes the breakdown of foods to COZ and HzO, storing the liberated chemical energy in molecules of ATP. Like myoglobin, it is an iron porphyrin protein, made up of one heme group and one polypeptide chain. The iron atomalternates between the +2 and +3 oxidation state as the molecule interacts in turn with cytochrome reductase and cytochrome oxidase, each a large multimolecular complex (l-3). One of the goals of the present x-ray analysis is to understand how electron. transfer occurs into and out of cytochrome c, which will ultimately require a knowledge of the molecular structure in both the ferric and ferrous states.
