| 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 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) |
| cytochrome p-450 cyp11b2 | <enzyme> A multifunctional enzyme that catalyses the conversion of corticosterone to 18-hydroxycorticosterone and the subsequent conversion of 18-hydroxycorticosterone to aldosterone. Registry number: EC 1.14.99.- (12 Dec 1998) |
| cytochrome p-450 cyp1a1 | <enzyme> A cytochrome p-450 enzyme capable of activating procarcinogenic polycyclic hydrocarbons and halogenated aromatic hydrocarbons into mutagenic compounds. Ethoxyresorufin acts as a substrate for cyp1a1 and measurement of ethoxyresorufin o-deethylase provides a more direct method of detection for this enzyme. Registry number: EC 1.- (12 Dec 1998) |
| cytochrome p-450 cyp1a2 | <enzyme> A polycyclic aromatic hydrocarbon-inducible cytochrome which is of significant clinical interest due to the large number of drug interactions associated with induction and inhibition of theophylline. Caffeine is considered to be a model substrate for this enzyme. It also metabolises theophylline and antipyrene. Environmental factors including cigarette smoking, charbroiled meat, cruciferous vegetables, and a number of drugs including phenytoin, phenobarbital, and omeprazole produce increases in cyp1a2 activity. Registry number: EC 1.- (12 Dec 1998) |
| cytochrome p-450 cyp2b1 | <enzyme> A major cytochrome p-450 enzyme which is inducible by phenobarbital in both the liver and small intestine. It is active in the metabolism of compounds like pentoxyresorufin, testosterone, and androstenedione. Cyp2b1 also mediates the activation of cyclophosphamide and ifosfamide to mutagens. Registry number: EC 1.- (12 Dec 1998) |
| cytochrome p-450 cyp2d6 | <enzyme> A polymorphic enzyme that catalyses the hydroxylation of debrisoquine. It also metabolises several antidepressants and neuroleptics. This enzyme is deficient in up to 10 percent of the population. Registry number: EC 1.14.99.- (12 Dec 1998) |
| cytochrome p-450 cyp2e1 | <enzyme> A polymorphic enzyme that activates carcinogenic n-nitrosamines, benzene, urethane, and other low molecular weight compounds. It is inducible by ethanol and metabilises alcohol. Experimentally, it is used to study the effects of ethanol usage and withdrawal via enzyme markers such as n-nitrosodimethylamine demethylase. Registry number: EC 1.5.99.- (12 Dec 1998) |
| 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 P-450-dependent digitoxin 12beta-hydroxylase | <enzyme> Isolated from digitalis lantata cell cultures Registry number: EC 1.14.99.- Synonym: digitoxin 12beta-hydroxylase (26 Jun 1999) |
| cytochrome P-450SCC | Cholesterol monooxygenase (side chain cleaving). Origin: 450 nm, the absorption maximum that the CO compound of the reduced pigment exhibits (05 Mar 2000) |
| 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) |
