Patent ID: 10526622

Abstract:
The present disclosure relates to the technical field of biochemical engineering and particularly discloses a preparation method for (R)-3-hydroxyl-5-hexenoate. In the method of the present disclosure, the (R)-3-hydroxyl-5-hexenoate is prepared by catalytic reduction of 3-carbonyl-5-hexenoate by ketoreductase with 3-carbonyl-5-hexenoate as the substrate. The amino acid sequence of ketoreductase is shown in SEQ ID NO.1. In the present disclosure, the (R)-3-hydroxyl-5-hexenoate having a very high chiral purity is obtained by asymmetric reduction by ketoreductase as the biocatalyst. The present disclosure has the advantages of easy operation, mild reaction conditions, high reaction yield and good practical industrial application value.
