− | < | + | <h4>We use CEAS2 enzyme as the core part, but acrylic acid is a byproduct of CEAS2 enzyme, the wild type 's catalytic effect is very weak, whose production is only 1mg/L. So we hope to improve the catalytic effect of CEAS2 enzyme.<br> |
We designed Ceas2 enzyme mutants via the AEMD(Auto Enzyme Mutation Design) platform and screened for better-worked Ceas2 mutants by HPLC(High Performance Liquid Chromatography) and HTS(High throughput screening). | We designed Ceas2 enzyme mutants via the AEMD(Auto Enzyme Mutation Design) platform and screened for better-worked Ceas2 mutants by HPLC(High Performance Liquid Chromatography) and HTS(High throughput screening). | ||
