||Dimethylaniline monooxygenase [N-oxide-forming] 5 is an enzyme that in humans is encoded by the FMO5 gene. Metabolic N-oxidation of the diet-derived amino-trimethylamine (TMA) is mediated by flavin-containing monooxygenase and is subject to an inherited FMO3 polymorphism in man resulting in a small subpopulation with reduced TMA N-oxidation capacity resulting in fish odor syndrome Trimethylaminuria. Three forms of the enzyme, FMO1 found in fetal liver, FMO2 found in adult liver, and FMO3 are encoded by genes clustered in the 1q23-q25 region. Flavin-containing monooxygenases are NADPH-dependent flavoenzymes that catalyzes the oxidation of soft nucleophilic heteroatom centers in drugs, pesticides, and xenobiotics.

||FMO′s are responsible for catalyzing the oxygenation of a variety of xenobiotic and drug compounds including environmental pollutants and carcinogens, which demonstrate a nucleophilic nitrogen, sulfur, selenium, and phosphorous-containing moiety associated with their respective oxides. These enzymes are classified as Phase I or oxidative drug metabolism enzymes. FMO5 is the only FMO isoform expressed in both adult and fetal human liver.
