In enzymology, L-erythro-3,5-diaminohexanoate dehydrogenase (EC 1.4.1.11) is an enzyme that catalyzes the chemical reaction

3,5-diaminohexanoic acid
+ NAD+
 
 
H2O

5-amino-3-oxohexanoic acid
+ NADH + NH3
 

The three substrates of this enzyme are L-erythro-3,5-diaminohexanoic acid, water, and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are (S)-5-amino-3-oxohexanoic acid, reduced NADH, ammonia, 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-erythro-3,5-diaminohexanoate:NAD+ oxidoreductase (deaminating). This enzyme is also called L-3,5-diaminohexanoate dehydrogenase. This enzyme participates in lysine degradation.
