Beta-alanopine dehydrogenase (EC 1.5.1.26) is an enzyme that catalyzes the chemical reaction

(R)-β-alanopine
+ NAD+
 
 
H2O
H+
H2O
H+
 
+ NADH +
 

The three substrates of this enzyme are (R)-β-alanopine, oxidised nicotinamide adenine dinucleotide (NAD+), and water. Its products are β-alanine, reduced NADH, pyruvic acid and a proton.[1] β-alanopine is a type of opine.[2]

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is N-(D-1-carboxyethyl)-beta-alanine:NAD+ oxidoreductase (beta-alanine-forming).
