A MUTANT LIPASE PROTEIN HAVING IMPROVED ENZYMATIC ACTIVITY GENE AND EXPRESSION VECTOR

摘要

The present invention relates to a method for screening of the lipase having improved enzymatic activity using yeast surface display vector and the mutant lipase prepared by the same, more particularly to the method comprising; 1) cloning lipase gene into surface display vector, 2) preparing mutant lipase gene library of the step 1 by mutagenic PCR, 3) transforming the mutant lipase gene library of the step 2 and surface display vector into host cell, and 4) measuring the activity of the mutant lipase displayed in the surface of the transformed host cell and selecting the mutant lipase prepared by the same. The method of the present invention can screen the lipase having improved enzymatic activity. So, it can effectively be used for the va...
