Name Dimethylaniline monooxygenase [N-oxide-forming] 2
Synonyms
  1. Dimethylaniline oxidase 2
  2. FMO 1B1
  3. FMO 2
  4. Pulmonary flavin-containing monooxygenase 2
Gene Name FMO2
Protein Type Unknown
Biological Properties
General Function Involved in flavin-containing monooxygenase activity
Specific Function Catalyzes the N-oxidation of certain primary alkylamines to their oximes via an N-hydroxylamine intermediate. Inactive toward certain tertiary amines, such as imipramine or chloropromazine. Can catalyze the S-oxidation of methimazole. The truncated form is catalytically inactive.
Pathways
  • Drug metabolism - cytochrome P450
