The function of Ensembl gene identifier ENSG00000094963 (FMO2, flavin containing dimethylaniline monoxygenase 2) is as follows. Catalyzes the oxidative metabolism of numerous xenobiotics, including mainly therapeutic drugs and insecticides that contain a soft nucleophile, most commonly nitrogen and sulfur and participates to their bioactivation (PubMed:15144220, PubMed:15294458, PubMed:18930751, PubMed:18948378, PubMed:9804831). Specifically catalyzes S-oxygenation of sulfur derived compounds such as thioureas-derived compounds, thioetherorganophosphates to their sulfenic acid (PubMed:15144220, PubMed:9804831). In vitro, catalyzes S-oxygenation of the second-line antitubercular drugs thiacetazone (TAZ) and ethionamide (ETA), forming a sulfinic acid and a carbodiimide via a postulated sulfenic acid intermediate (PubMed:18930751, PubMed:18948378). Also catalyzes S- oxygenation of the thioether-containing organophosphate insecticides, phorate and disulfoton (PubMed:15294458). {ECO:0000269|PubMed:15144220, ECO:0000269|PubMed:15294458, ECO:0000269|PubMed:18930751, ECO:0000269|PubMed:18948378, ECO:0000269|PubMed:9804831}.
