Claim: The enzyme alanopine dehydrogenase in the oxidoreductases with two substrates catalyzes the chemical reaction and has four products.
Evidence: Alanopine dehydrogenase (EC ) is an enzyme that catalyzes the chemical reaction 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 2 substrates of this enzyme are 2,2'-iminodipropanoate, and nicotinamide adenine dinucleotide+. Its 4 products are L-alanine, pyruvate, nicotinamide adenine dinucleotide, and hydrogen ion.
