报告摘要:Enzyme catalysis has emerged as an indispensable tool in the industrial sector, offering environmentally benign alternatives to traditional chemical processes by utilizing enzymes and whole cells to catalyze chemical reactions. Despite its growing importance, the industry faces several considerable challenges: 1) narrow substrate scope of enzymes, and 2) the poor solubility of substrates in the reaction medium (water). These challenges make us difficult to use nature enzymes for many reactions of our interests.
We are working at the interface of polymer science and enzyme catalysis, focusing on combining polymers with enzymes for new-to-nature applications. Specifically, I will present a new approach to preparing artificial enzymes by combining proteins with catalytically active polymers, generating so-called “artificial polyenzymes” (ArPoly). Different from traditional artificial enzymes, ArPoly can be easily tailored for their structure, composition, catalysis loading, and active sites, which allows their high reactivity and new-to-nature selectivity. Furthermore, we developed enzyme-polymer conjugates and block copolymers as new type of emulsifiers for various emulsions for recyclable biocatalysis, which is particularly effective to reactions involving with nonpolar substrates. Recently, we even integrated supramolecular polymers with enzymes, creating supramolecular enzymes (SupEnzyme), which makes nature enzymes with supramolecular properties for industrial biotechnology.
