FMO3: Lysates

The mammalian flavin-containing monooxygenases (FMO; EC 1.14.13.8) represent a multigene family whose gene products are localized in the endoplasmic reticulum of many tissues. These enzymes catalyze the NADPH-dependent oxidative metabolism of many drugs, pesticides, and other foreign compounds. Their substrates are soft nucleophiles with an electron-rich center, typically a nitrogen, sulfur or phosphorus-containing functional group, as the site for oxidative attack by the enzyme (Ziegler, 1990 [PubMed 2203193]; Hines et al., 1994 [PubMed 8128486]).[supplied by OMIM]
