Abstract

Use of a stereoselective transaminase in the asymmetric synthesis of a chiral amine. In particular, provided is use of a polypeptide in the production of a chiral amine or a downstream product using a chiral amine as a precursor. Further provided is a method for producing a chiral amine, comprising culturing a strain expressing the polypeptide so as to obtain a chiral amine. Further provided are novel prochiral compounds, a chiral amine production strain and a method for constructing the chiral amine production strain. The stereoselective transaminase has a broad substrate spectrum and thus has a broad application potential in the preparation of a chiral amine.

wherein,

R 1 is selected from the group consisting of none, oxo (═O), halogen, —OH, —NH 2 , substituted or unsubstituted C1-C 8 alkyl, substituted or unsubstituted C 3 -C 8 cycloalkyl, substituted or unsubstituted C 1 -C 8 alkoxy, substituted and unsubstituted C 3 -C 8 cycloalkoxy;

R 2 is selected from the group consisting of none, halogen, —OH, —NH 2 , substituted or unsubstituted C 1 -C 8 alkyl, substituted or unsubstituted C 3 -C 8 cycloalkyl, substituted or unsubstituted C 1 -C 8 alkoxy, substituted and unsubstituted C 3 -C 8 cycloalkoxy;

X is selected from the group consisting of: C and N;

Y is selected from the group consisting of: C, N, O, and S;
