| 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 |
A type of protein whose function is to carry electrons or protons (hydrogen ions) by virtue of the reversible charging/discharging of an iron atom or iron/sulfur atoms in the center of the protein. Cytrochromes are central molecules of electron transport in the process known as oxidative phosphorylation. The "chrome" means color, and these cytochromes are divided into four groups. (a, b, c, d) according to their ability to absorb or transmit certain colors of light.
