Nomenclature
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.
