Abstract: The stereoselective oxidation of an unreactive alkane C-H bond is most often carried out by monoxygenases or oxygenases including dioxygenases which use iron as a cofactor and constitute a family of enzymes, e.g. Redox enzymes. A dioxygenase is an enzyme which incorporates both the atoms of molecular oxygen into kinds of substrates. The oxidative transformation reactions are common reactions during fruit ripening and Abscisic acid biosynthesis in strawberries. The main substrate of 2-OG (orthoglutarate) dependent dioxygenases is glutarate which is converted in succinate during flavor biogenesis.
