Diaphorase are dehydrogenase enzymes which catalyze the dehydrogenation of the reduced forms of the co-enzyme NADH and NADPH. NADH and NADPH originally come from purified extracts of Clostridium kluyveri cells, where diaphorase activity is shown. Other diaphorase activities come from various bacteria, plants and mammalian organs. This enzyme was isolated from Bacillus megaterium.
Applications:
• Used in the reoxidation of NADP to NADPH
• Used to construct a biosensor for acetaldehyde by immobilization
