We report on artificial metalloenzymes that incorporate a biotinylated dirhodium core embedded within engineered streptavidin (Sav hereafter) variants. The resulting biohybrid catalyzes the carbene insertion in C–H bonds and olefins. Chemical- and genetic optimization allows to modulate the catalytic activity of the artificial metalloenzymes that are shown to be active in the periplasm of E. coli (up to 20 turnovers).

基于锚定在链霉亲和素中的生物素化的铑,用于卡宾转移的人工金属酶

我们报道了人工金属酶,其中掺入了工程化的链霉亲和素(以下简称Sav)变体中嵌入的生物素化的dirhodium核心。由此产生的生物杂化催化了碳烯在C–H键和烯烃中的插入。化学和遗传优化可调节人工金属酶的催化活性,该酶在大肠杆菌的周质中具有活性(最多20个转换)。
