N6 methyl lysine oxidase

In enzymology, a N6-methyl-lysine oxidase (EC 1.5.3.4) is an enzyme that catalyzes the chemical reaction

The 3 substrates of this enzyme are N6-methyl-L-lysine, H₂O, and O₂, whereas its 3 products are L-lysine, 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 N6-methyl-L-lysine:oxygen oxidoreductase (demethylating). Other names in common use include epsilon-alkyl-L-lysine:oxygen oxidoreductase, N6-methyllysine oxidase, epsilon-N-methyllysine demethylase, epsilon-alkyllysinase, and 6-N-methyl-L-lysine:oxygen oxidoreductase (demethylating).
