In enzymology, a N-methyl-L-amino-acid oxidase (EC 1.5.3.2) is an enzyme that catalyzes the chemical reaction

an N-methyl-L-amino acid + H₂O + O₂ $\rightleftharpoons$ an L-amino acid + formaldehyde + H₂O₂

The 3 substrates of this enzyme are N-methyl-L-amino acid, H₂O, and O₂, whereas its 3 products are L-amino acid, formaldehyde, and H₂O₂.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with oxygen as acceptor. The systematic name of this enzyme class is N-methyl-L-amino-acid:oxygen oxidoreductase (demethylating). Other names in common use include N-methylamino acid oxidase, and demethylase. It has 2 cofactors: FAD, and Flavoprotein.
