Patent ID: 10131889

Abstract:
The present invention relates to the field of bioengineering. It provides a Candida antarctica lipase B mutant and its application. The mutant enzyme overcomes the limit of the parent enzyme that can exhibit high enantioselectivity towards (R)-3-TBDMSO glutaric acid methyl monoester only at temperatures below 5° C. The mutant enzyme successfully increased R-ee value at 5-70° C. The mutant D223V/A281S exhibits high R-ee value (>99%), high conversion rate (80%), and high space-time yield (107.54 g L−1 d−1). The present invention lays a foundation for industrial production of (R)-3-TBDMSO glutaric acid methyl monoester using a biosynthesis approach and provide insights into conformational dynamics-based enzyme design.
