Claim: 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 hydrogen ion.
Evidence: 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.
