The present invention relates to a method for producing an optically-active amine compound. The method is characterized by using a transaminase (A), an α-keto acid reductase (B), and an enzyme (C), each having specific properties, in an identical reaction system to convert a ketone compound into a corresponding optically-active amine compound in which a carbon atom with an amino group bonded thereto serves as an asymmetric point. The present invention also relates to a recombinant vector for use in the method. The present invention makes it possible to efficiently produce an optically-active amine compound.
