1 Recent studies have shown that UGT2B10 is a major enzyme involved in the N-glucuronidation of several tobacco-specific nitrosamines. Nitrogen UDP glucuronosyltransferase family 2 member B10 Homo sapiens
2 In the present study, microsomes of UGT2B10-overexpressing HEK293 cells exhibited high N-glucuronidation activity against both nicotine and cotinine with apparent KM"s that were 37- and 3-fold lower than that observed for microsomes of UGT1A4-overexpressing cells against nicotine and cotinine, respectively. Nitrogen UDP glucuronosyltransferase family 2 member B10 Homo sapiens
3 These data suggest that UGT2B10 is the major hepatic enzyme involved in nicotine/cotinine glucuronidation and that the UGT2B10*2 variant significantly reduces nicotine- and cotinine-N-glucuronidation formation and plays an important role in nicotine metabolism and elimination. Nitrogen UDP glucuronosyltransferase family 2 member B10 Homo sapiens
