Alanopine dehydrogenase is in the oxidoreductases family and has four products with hydrogen ion as one of them.
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. In biochemistry, an oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule, the reductant, also called the electron donor, to another, the oxidant, also called the electron acceptor. Its 4 products are L-alanine, pyruvate, nicotinamide adenine dinucleotide, and hydrogen ion.
