| cytochrome C | A type of cytochrome, a protein which carries electrons, that is central to the process of respiration in mitochondria (an organelle found in eukaryotes which produces energy). (09 Oct 1997) |
|---|---|
| cytochrome c1 | <chemical> The 30-kD membrane-bound c-type protein of mitochondria that functions as an electron donor to cytochrome c in the mitochondrial and bacterial respiratory chain. Chemical name: Cytochrome c1 (12 Dec 1998) |
| cytochrome C1 haem lyase | <enzyme> A mitochondrial haem lyase from saccharomyces cerevisiae; mw about 31 kD; facilitates covalent attachment of haem to the apoforms of c-type cytochromes Registry number: EC 4.99.- Synonym: yeast cc1hl (26 Jun 1999) |
| cytochrome c2 reductase | <enzyme> An enzyme catalyzing the reduction of 2 ferricytochrome c2 to 2 ferrocytochrome c2 at the expense of NADPH. Synonym: cytochrome c2 reductase. (05 Mar 2000) |
| cytochrome c3 hydrogenase | A hydrogenase enzyme catalyzing reduction of 2ferricytochrome c3 by H2 to 2ferrocytochrome c3 and 2H+. (05 Mar 2000) |
| cytochrome C553 peroxidase | <enzyme> A haem group of cytochrome-c peroxidase (EC 1.11.1.5); catalytically active in both the oxidised and half-reduced states; from nitrosomonas europaea; partial amino acid sequence given in first source Registry number: EC 1.11.1.- (26 Jun 1999) |
| cytochrome cd | cytochrome oxidase (Pseudomonas) |
| cytochrome C hydrolase | <enzyme> From yeast mitochondrial inner membrane Registry number: EC 3.4.- (26 Jun 1999) |
| cytochrome C-methionine methyltransferase | <enzyme> Forms s-methylmethionine Registry number: EC 2.1.1.- Synonym: cyt c-met methyltransferase (26 Jun 1999) |
| cytochrome C methyltransferase | <enzyme> From crithida oncopelti Registry number: EC 2.1.1.- (26 Jun 1999) |
| cytochrome-c peroxidase | <enzyme> A haemprotein which catalyses the oxidation of ferrocytochrome c to ferricytochrome c in the presence of hydrogen peroxide. Chemical name: Ferrocytochrome c:hydrogen-peroxide oxidoreductase Registry number: EC 1.11.1.5 (12 Dec 1998) |
| cytochrome c reductase | <enzyme> A flavoprotein containing iron. Cytochrome c may act as receptor. The enzyme reversibly catalyses the oxidation of NADH to NAD and reduced acceptor. An inherited deficiency of this complex results in overwhelming acidosis. Synonym: cytochrome c reductase. Chemical name: NADH:(acceptor) oxidoreductase Registry number: EC 1.6.99.3 (12 Dec 1998) |
| cytochrome C synthetase | <enzyme> Forms cytochrome c from the apoprotein + hemin, requires NADPH; mechanism not given 9/81 Registry number: EC 4.99.- Synonym: cytochrome c haem lyase, hccs gene product (26 Jun 1999) |
| cytochrome d | <chemical> 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. Chemical name: Cytochrome d (12 Dec 1998) |
| cytochrome p-450 | <biochemistry> Enzymes of the electron transport chain that are pigmented by virtue of their haem prosthetic groups. They are highly conserved isozymes which are key components of the mixed-function oxidase system responsible for the biotransformation of many foreign compounds to mutagens and carcinogens. Most mammals have several distantly related phenobarbital-inducible gene subfamilies. (21 Jun 2000) |
