The 3 substrates of this enzyme are L-lysine, O2, and H2O, whereas its 3 products are 2-aminoadipate 6-semialdehyde, H2O2, and NH3.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH2 group of donors with oxygen as acceptor. The systematic name of this enzyme class is L-lysine:oxygen 6-oxidoreductase (deaminating). Other names in common use include L-lysine-epsilon-oxidase, Lod, LodA, and marinocine.
