Other Information

**Key Characteristics** CYP2B6 is a member of the cytochrome P450 family, which is characterized by the presence of a heme group and a flavin moiety. The enzyme is a monooxygenase, meaning it catalyzes the incorporation of one atom of oxygen into a substrate. CYP2B6 is a cytochrome P450 enzyme, which means it contains a heme group and is involved in the oxidation of substrates. The enzyme is also a member of the CYP2 subfamily, which is characterized by the presence of a specific amino acid sequence. **Pathways and Functions** CYP2B6 is involved in the metabolism of a wide range of substrates, including: * Anandamide: CYP2B6 catalyzes the epoxidation of anandamide, a cannabinoid neurotransmitter, to form 11,12-dihydroanandamide. * Arachidonic acid: CYP2B6 catalyzes the epoxidation of arachidonic acid to form epoxyeicosatrienoic acid (EET), which is involved in various cellular processes, including inflammation and cell signaling. * Xenobiotics: CYP2B6 is involved in the metabolism of various xenobiotics, including drugs, such as cyclophosphamide and carbamazepine, and environmental toxins, such as polycyclic aromatic hydrocarbons (PAHs). * Steroids: CYP2B6 is involved in the metabolism of various steroids, including testosterone and estrogen. **Clinical Significance** CYP2B6 is involved in the metabolism of various drugs, including: * Cyclophosphamide: CYP2B6 is involved in the metabolism of cyclophosphamide, a chemotherapeutic agent, and its metabolite, acrolein, which can cause toxicity. * Carbamazepine: CYP2B6 is involved in the metabolism of carbamazepine, an anticonvulsant agent, and its metabolite, phenylacetylglutamine, which can cause toxicity. * Methadone: CYP2B6 is involved in the metabolism of methadone, an opioid analgesic, and its metabolite, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), which can cause toxicity. * Cannabinoids: CYP2B6 is involved in the metabolism of cannabinoids, including THC, the active metabolite of cannabis. Polymorphisms in the CYP2B6 gene can affect the metabolism of these drugs and may contribute to adverse drug reactions. Therefore, CYP2B6 is an important enzyme in the context of pharmacogenomics and personalized medicine. In addition to its role in drug metabolism, CYP2B6 is also involved in the regulation of various cellular processes, including inflammation, cell signaling, and metabolism. Alterations in CYP2B6 expression or activity may contribute to various diseases, including cancer, cardiovascular disease, and neurological disorders. In conclusion, CYP2B6 is an important enzyme involved in the metabolism of a wide range of substrates, including drugs, hormones, and toxins. Its polymorphisms can affect the metabolism of drugs and may contribute to adverse drug reactions. Further research is needed to fully understand the role of CYP2B6 in human health and disease.
