Lysine dehydrogenase
In enzymology, a lysine dehydrogenase (EC1.4.1.15) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are L-lysine and NAD, whereas its 4 products are 1,2-didehydropiperidine-2-carboxylate, NH3, NADH, and H.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH2 group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is L-lysine:NAD+ oxidoreductase (deaminating, cyclizing).
