| cytochrome P-450 oxidase | <enzyme> Oxidises NADPH with formation of hydrogen peroxide Registry number: EC 1.6.2.- Synonym: NADPH-p450 reductase, NADPH-cytochrome p450 reductase, cytochrome p450 reductase, cpra gene product (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 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) |
| Pseudomonas cytochrome oxidase | <enzyme> Catalyses conversion of ferrocytochrome to ferricytochrome utilizing nitrate as oxidizing agent Registry number: EC 1.9.3.2 Synonym: cytochrome cd, nitrosyl nitrite reductase, cytochrome c,d1, dissimilatory nitrite reductase, cytochrome cd1 nitrite reductase, cd1-dnir, cd1-dnirs, pseudomonas aeruginosa nitrite reductase, nitrite reductase, ps. Aeruginosa (26 Jun 1999) |

| cytochrome | <biochemistry> Any electron transfer haemoprotein having a mode of action in which the transfer of a single electron is effected by a reversible valence change of the central iron atom of the haem prosthetic group between the +2 and +3 oxidation states. Classified as cytochromes a in which the haem contains a formyl side chain, cytochromes b, which contain protohaem or a closely similar haem that is not covalently bound to the protein, cytochromes C in which protohaem or other haem is covalently bound to the protein and cytochromes d in which the iron tetrapyrrole has fewer conjugated double bonds than the haems have. Well known cytochromes have been numbered consecutively within groups and are designated by subscripts (beginning with no subscript), for example cytochromes C, c1, C2,. New cytochromes are named according to the wavelength in nanometres of the absorption maximum of the a band of the iron (II) form in pyridine, for example, C 555. Origin: Gr. Chroma = colour (18 Nov 1997) |
| cytochrome a | <chemical> Cytochromes (electron-transporting proteins) in which the haem prosthetic group is haem a, i.e., the iron chelate of cytoporphyrin ix. Chemical name: Cytochrome a (12 Dec 1998) |
| cytochrome aa3 | <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.
