| cytochrome b5 reductase | <enzyme> An enzyme catalyzing the reduction of 2ferricytochrome b5 to 2ferrocytochrome b5 at the expense of NADH; has a role in fatty acid desaturation; a deficiency can lead to hereditary methemoglobinaemia (type I, only observed in erythrocyte cytosol; type II, deficiency in all tissues; type III, deficiency in all haematopoetic cells). (05 Mar 2000) |
|---|---|
| cytochrome b(5) reductase | <enzyme> May be the enzyme for methemoglobin reductase activity Registry number: EC 1.6.2.2 Synonym: NADH-cytochrome b5 reductase, mcr1 protein, saccharomyces cerevisiae, mcr1 gene product (26 Jun 1999) |
| 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.
