N,N-dimethylaniline + NADPH + H+ + O2 = N,N-dimethylaniline N-oxide + NADP+ + H2O
catalytic reaction mechanism, structure-function relationship, FMO oxygenates soft nucleophiles, and converts lipophilic compounds into more hydrophilic metabolites, the first step for FMO is reduction of the FAD by NADPH, the next step is formation of a C4a-hydroperoxy flavin by addition of molecular oxygen to the reduced FAD, when the substrate is accepted by FMO the enzyme is already in an active form, the protein environment of FMO apparently protects the hydroperoxy flavin from decomposing, conserving NADPH, and affording an effcient two-electron oxygenating agent for nucleophiles with the appropriate size and shape

SYSTEMATIC NAME
IUBMB Comments
N,N-dimethylaniline,NADPH:oxygen oxidoreductase (N-oxide-forming)
A flavoprotein. A broad spectrum monooxygenase that accepts substrates as diverse as hydrazines, phosphines, boron-containing compounds, sulfides, selenides, iodide, as well as primary, secondary and tertiary amines [3,4]. This enzyme is distinct from other monooxygenases in that the enzyme forms a relatively stable hydroperoxy flavin intermediate [4,5]. This microsomal enzyme generally converts nucleophilic heteroatom-containing chemicals and drugs into harmless, readily excreted metabolites. For example, N-oxygenation is largely responsible for the detoxification of the dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) [2,6]

additional information
-
although maltose-binding-protein-FMO enzymes afford lower rates of turnover than the corresponding commercial recombinant FMOs, both types of FMO show identical substrate dependencies and similar responses to changes in assay conditions. Comparison of commercial recombinant enzymes with recombinant MBP-FMOs expressed in Escherichia coli, overview
additional information
chromatin immunoprecipitation assays do not detect recruitment of aryl hydrocarbon receptor or ARNT to Fmo3 regulatory elements after exposure to 3-methylcholanthrene in liver or in Hepa-1 cells. However, in Hepa-1, 3-methylcholanthrene and benzo[a]pyrene , but not 2,3,7,8-tetrachlorodibenzo-p-dioxin, cause recruitment of p53 protein to a p53 response element in the 5'-flanking region of the Fmo3 gene. Although FMO3 mRNA is highly induced by 3-methylcholanthrene or 2,3,7,8-tetrachlorodibenzo-p-dioxin in mouse liver and in Hepa-1 cells, FMO protein levels and FMO catalytic function show only modest elevation
