Mutant amino acid oxidase and method for de-racemization of racemic form of amine compound

摘要

The purpose of the present invention is to provide a method of efficiently producing an α-amino nitrile compound from a non-cyclic amine compound. The production method for an α-alkylamino nitrile compound according to the present invention is characterized by subjecting a specific non-cyclic amine compound to the action of an amino acid oxidase to produce an imine compound, which is then subjected to the action of cyanide ions to obtain an α-alkylamino nitrile compound.
