Cytochrome c (550, T. novellus) is rather similar to the mammalian-type cytochrome c in spite of its bacterial origin (Yamanaka, 1972a, b). J Biol Inorg Chem. In contrast, the catalase was mostly in the cytoplasmic fraction. Cytochrome c is not an integral part of complex IV, but is stoichiometrically associated with it and is believed to be spatially associated with subunit II of cytochrome oxidase.
