In enzymology, lysine dehydrogenase (EC 1.4.1.15) is an enzyme that catalyzes the chemical reaction

+ NAD+
 
 
 
NH3 + H+
Lysine dehydrogenase
 
NH3 + H+
 
+ NADH
 

The two substrates of this enzyme are L-lysine and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 1-piperideine-2-carboxylic acid, ammonia, reduced NADH, and a proton. [1] [2]

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).
