Abstract: Provided are an esterase mutant and the use thereof. The esterase mutant obtained by means of rational design and several rounds of evolution screening with enzymes on the basis of an amino acid sequence as shown in SEQ ID NO: 1 is changed in terms of protein structure and function compared with a wild-type esterase; in practical use, the catalytic activity and/or stereoselectivity of the esterase mutant is greatly improved; and when a system contains some organic cosolvents, the esterase mutant still has relatively stable catalytic activity and/or stereoselectivity. In addition, the improvement of the catalytic activity and/or stereoselectivity of the esterase mutant reduces the use amount of the enzyme to a certain extent and reduces the difficulty of post-treatment, and therefore the esterase mutant is suitable for industrial production.
