Abstract

The development of artificial metalloenzymes (ArMs) offers a potent approach to incorporate non-natural chemical reactions into biocatalysis. Here we report the assembly of Mn(salen)-based ArMs by embedding biotinylated Mn(salen) complexes into streptavidin (Sav) variants. Using commercially available nitrene and oxo transfer reagents, these biohybrid catalysts catalyzed the aziridination of alkenes and oxidation of benzylic C-H bonds with up to 19 and 146 turnover numbers.

人工金属酶（ArMs）的开发为将非天然化学反应纳入生物催化提供了一种有效的方法。在此，我们报告了通过将生物素化的锰（沙伦）复合物嵌入链霉亲和素（Sav）变体，组装出基于锰（沙伦）的 ArMs。这些生物杂化催化剂使用市售的腈类和氧转移试剂，催化了烯类的叠氮化反应和苄基 C-H 键的氧化反应，周转次数分别高达 19 次和 146 次。
