Opine dehydrogenase is an enzyme that belongs to the family ofoxidoreductases, it has three substrates (which is typically thechemical speciesbeing observed in achemical reaction, which reacts with areagentto generate aproduct), these are [[(2S)-2-{[1-(R)-carboxyethyl]amino}pentanoate]],NAD, andH2O, and four products,L-2-aminopentanoic acid,pyruvate,NADH, andH.
In enzymology, an opine 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 3 substrates of this enzyme are NAD, and H2O, whereas its 4 products are L-2-aminopentanoic acid, pyruvate, NADH, and H. In chemistry, a substrate is typically the chemical species being observed in a chemical reaction, which reacts with a reagent to generate a product.
