The invention relates to a site-directed mutagenesis modified saccharomyces cerevisiae dipeptidyl peptidase III. The site-directed mutagenesis modified saccharomyces cerevisiae dipeptidyl peptidase III is characterized in that the site-directed mutagenesis modified saccharomyces cerevisiae dipeptidyl peptidase III is a mutant generated by substitution of multiple amino acids in saccharomyces cerevisiae dipeptidyl peptidase III derived from saccharomyces cerevisiae S288c and having an amino acid sequence being SEQ ID NO.1, substitution of the multiple amino acids refers to substitution of a 570th site, a 572th site and a 574th site, and the site-directed mutagenesis modified saccharomyces cerevisiae dipeptidyl peptidase III is modified into an enzyme with an oxygenolysis effect on 6-methoxy di-furocoumarin. The site-directed mutagenesis modified saccharomyces cerevisiae dipeptidyl peptidase III can be applied to preparation of products for removing the 6-methoxy di-furocoumarin from feedstuffs, additives of the feedstuffs, foods and additives of the foods and can be further applied to preparation of medicines for preventing diseases induced by the 6-methoxy di-furocoumarin.
