Moreover, aflatoxin B1-DNA adducts can result in GC to TA transversions. Cytochrome P450 enzymes are considered nanomachines and they carry out their enzymatic reactions by means of a catalytic cycle. Cytochrome P450 enzymes are subdivided into classes (e.g. Each member of a family contains similar amino acids. Rendic S, Di Carlo FJ (1997) Human cytochrome P450 enzymes: a status report summarizing their reactions, substrates, inducers, and inhibitors. 2 Genetik. These isoforms are given numbers and letters to signify their common evolutionary families. Instead CYPs appear to have specific functions in brain, e.g. 3A only), or they may be metabolized by a number of CYP enzymes (ex.

Cytochrome P450 2E1 (abbreviated CYP2E1, EC 1.14.13.n7) is a member of the cytochrome P450 mixed-function oxidase system, which is involved in the metabolism of xenobiotics in the body. The known … Search for more papers by this author. Thus, the stimulatory effect of OOO-Et(S) on microsomal NADPH-cyto- chrome c reductase activity is a rather unusual effect of an inhibitor of the cytochrome P-450 system.
