Aspartate dehydrogenase is an enzyme that catalyzes the chemical reaction where the 4 substrates of this enzyme are L-aspartate, water, nicotinamide adenine dinucleotide ion, and nicotinamide adenine dinucleotide phosphate ion (a cofactor used in anabolic reactions, such as the Calvin cycle and lipid and nucleic acid syntheses, which require NADPH as a reducing agent).
Aspartate dehydrogenase (EC ) is an enzyme that catalyzes the chemical reaction The 4 substrates of this enzyme are L-aspartate, water, nicotinamide adenine dinucleotide ion, and nicotinamide adenine dinucleotide phosphate ion, whereas its 5 products are oxaloacetate, ammonia, NADH, nicotinamide adenine dinucleotide phosphate, and hydrogen ion. Nicotinamide adenine dinucleotide phosphate, abbreviated NADP or, in older notation, TPN (triphosphopyridine nucleotide), is a cofactor used in anabolic reactions, such as the Calvin cycle and lipid and nucleic acid syntheses, which require NADPH as a reducing agent.
