Using a protein scaffold covalently functionalised with a thiamine-inspired N-heterocyclic carbene (NHC), we created an artificial Stetterase (ArtiSt) which catalyses a stereoselective, intramolecular Stetter reaction. We demonstrate that ArtiSt functions under ambient conditions with low catalyst loading. Furthermore, activity can be increased >20 fold by altering the protein scaffold.
我们使用一种通过硫胺素启发的 N-杂环卡宾（NHC）共价功能化的蛋白质支架，创建了一种人工 Stetterase（ArtiSt），它可以催化立体选择性的分子内 Stetter 反应。我们证明了 ArtiSt 在低催化剂负载下的环境条件下起作用。此外，通过改变蛋白质支架，活性可以增加 20 倍以上。
