 Synonyms & Historicals
Cytochromes .
Cytochrome .
Hemeproteins whose characteristic mode of action involves transfer of reducing equivalents which are associated with a reversible change in oxidation state of the prosthetic group. Formally, this redox change involves a single-electron, reversible equilibrium between the Fe(II) and Fe(III) states of the central iron atom (From Enzyme Nomenclature, 1992, p539). The various cytochrome subclasses are organized by the type of HEME and by the wavelength range of their reduced alpha-absorption bands. .
Cytochromes a .
Cytochrome a .
A subclass of heme a containing cytochromes that have two imidazole nitrogens as axial ligands and an alpha-band absorption of 605 nm. They are found in a variety of microorganisms and in eucaryotes as a low-spin cytochrome component of MITOCHONDRIAL ELECTRON TRANSPORT COMPLEX IV. .
Cytochromes c' .
Cytochrome c' .
Cytochromes c Prime .
Ferricytochrome c' .
A widely occurring subclass of c type cytochromes which function as electron carriers in the electron transport chain in photosynthetic and denitrifying BACTERIA. .
Cytochromes c .
Apocytochrome C .
Cytochrome c .
Ferricytochrome c .
Ferrocytochrome c .
Cytochromes of the c type that are found in eukaryotic MITOCHONDRIA. They serve as redox intermediates that accept electrons from MITOCHONDRIAL ELECTRON TRANSPORT COMPLEX III and transfer them to MITOCHONDRIAL ELECTRON TRANSPORT COMPLEX IV. .
Cytochromes b .
Apocytochrome b .
Cytochrome b .
Cytochromes of the b group that have alpha-band absorption of 563-564 nm. They occur as subunits in MITOCHONDRIAL ELECTRON TRANSPORT COMPLEX III. .
Cytochrome d Group .
Cytochrome d .
Cytochromes d .
Cytochromes (electron-transporting proteins) with a tetrapyrrolic chelate of iron as a prosthetic group in which the degree of conjugation of double bonds is less than in porphyrin. (From Enzyme Nomenclature, 1992, p539) .
