L lysine 6 oxidase

In enzymology, a L-lysine 6-oxidase (EC 1.4.3.20) is an enzyme that catalyzes the chemical reaction

L-lysine + O₂ + H₂O ⇌ 2-aminoadipate 6-semialdehyde + H₂O₂ + NH₃

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.
