| 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 oxidase | <enzyme> An enzyme complex of the inner mitochondrial membrane that catalyses the reaction between ferrocytochrome c and oxygen to yield ferricytochrome c and water. It is associated with the pumping of protons and the resultant phosphorylation of ADP to ATP. The reaction is the terminal event in the electron transport scheme by which oxygen is used for fuel combustion. It is a part of Complex IV of the respiratory chain. A deficiency of one or more of the polypeptides of this complex results in neuronal loss in brain leading to psychomotor retardation and neurodegenerative disease. Synonym: cytochrome aa3, indophenol oxidase, indophenolase. Chemical name: Ferricytochrome-c:oxygen oxidoreductase Registry number: EC 1.9.3.1 (12 Dec 1998) |
| 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 oxidase | <enzyme> Terminal enzyme of the electron transport chain that accepts electrons from (i.e. Oxidizes) cytochrome C and transfers electrons to molecular oxygen. (18 Nov 1997) |
| cytochrome peroxidase | A haemoprotein enzyme catalyzing the reaction between H2O2 and 2 ferrocytochrome c to yield 2ferricytochrome c and 2H2O. (05 Mar 2000) |
| cytochrome reductase | <enzyme> A flavoprotein that catalyses the reduction of haem-thiolate-dependent monooxygenases and is part of the microsomal hydroxylating system. Its physiological acceptor is probably cytochrome p-450. Chemical name: NADPH:ferrihemoprotein oxidoreductase Registry number: EC 1.6.2.4 (12 Dec 1998) |
| cytochrome reductases | <enzyme> Registry number: EC 1.6.2. (12 Dec 1998) |
| cytochrome system | The mitochondrial electron transport chain. (18 Nov 1997) |
