| succinate cytochrome c oxidoreductase | <enzyme> A portion of the electron transport chain, catalyzing the transfer of electrons from succinate to cytochrome c via fad, ubiquinone, and cytochrome b. The first step is catalyzed by succinate dehydrogenase (ec 1.3.99.1), the other steps are not well characterised. Registry number: EC 1.- (12 Dec 1998) |

| QH2 cytochrome C reductase | <enzyme> Membrane bound complex in the mitochondrial inner membrane, responsible for electron transfer from reduced coenzyme Q to cytochrome C. Contains cytochromes b and c1 and iron sulphur proteins. (18 Nov 1997) |
| triazole cytochrome P-450-obtusifoliol-14-demethylase | <enzyme> Key enzyme in plant sterol biosynthesis Registry number: EC 1.- Synonym: tcpo demethylase, obtusifoliol 14 alpha-methyl demethylase (26 Jun 1999) |
| ubiquinol-cytochrome-c reductase | <enzyme> An 11-subunit enzyme complex that acts as an electron transferring protein in the mitochondrial respiratory chain. The enzyme complex catalyses the oxidation of ubiquinol to ubiquinone and ferrocytochrome c in the presence of ferricytochrome c. It contains cytochromes b-562, b-566, and c1 as well as an iron ferredoxin. Chemical name: Ubiquinol-ferricytochrome-c oxidoreductase Registry number: EC 1.10.2.2 (12 Dec 1998) |
