The invention discloses a Bayer Williger monooxygenase mutant and an application of the Bayer Williger monooxygenase mutant. The invention provides a monooxygenase mutant, and compared with an amino acid sequence shown as SEQ ID NO: 1, an amino acid sequence of the monooxygenase mutant contains amino acid residue difference of one or more sites; the activity of the monooxygenase mutant is improved compared with that of Bayer-Williger monooxygenase with the amino acid sequence shown as SEQ ID NO: 1, wherein the amino acid sequence of the Bayer-Williger monooxygenase is shown as SEQ ID NO: 1. According to the monooxygenase mutant provided by the invention, the chiral thiosulfinate compound can be generated with relatively high yield and stereoselectivity, and the reaction condition is mild.
