Dehydrogenases are family of enzymes belonging to the group oxidoreductase. These enzymes catalyze the oxidation of a substrate by transferring one or more hydrides to an electron acceptor or coenzyme. Common electron acceptors, being considered as oxidizers of the substrate are usually nicotinamide adenine dinucleotide (NAD+/NADH), nicotinamide adenine dinucleotide phosphate (NADP+/NADPH), flavin adenine dinucleotide (FAD) or flavin mononucleotide (FMN).
AAT Bioquest has developed a variety of optical assay kits either for detecting specific dehydrogenases targets such as Glucose-6-Phosphate Dehydrogenase and Lactate Dehydrogenase, or for general dehydrogenases based on the change of NAD+/NADH and NADP+/NADPH.
