The Dehydrogenase, malate, with the CAS registry number 9001-64-3, is also known as Malic acid dehydrogenase. It belongs to the product category of Enzymes. Its EINECS number is 232-622-5. Its EC number is 1.1.1.37. Its classification code is TSCA Flag XU [Exempt from reporting under the Inventory Update Rule]. It is an enzyme in the citric acid cycle that catalyzes the conversion of malate into oxaloacetate (using NAD+) and vice versa (this is a reversible reaction). Malate dehydrogenase is not to be confused with malic enzyme, which catalyzes the conversion of malate to pyruvate, producing NADPH. Malate dehydrogenase is also involved in gluconeogenesis, the synthesis of glucose from smaller molecules. The active site of malate dehydrogenase is a hydrophobic cavity within the protein complex that has specific binding sites for the substrate and its coenzyme, NAD+. It is stable at common pressure and temperature, and it should be sealed and stored in a cool and dry place with the storage temperature of 2-8 °C. Moreover, it should be protected from light, moisture and heat. You should not breathe dust. When using it, you must avoid contact with eyes.
