Whole-cell E. coli platform enables directed evolution campaigns with ArMs containing an abiotic Ir-porphyrin cofactor involving the generation of more than 4000 mutants to develop an enantioselective insertion of a simple acyclic carbene from a diazo ester into the N−H bond of N-methyl aniline that has formed product with poor enantioselectivity when catalyzed by prior enzyme systems.
全细胞大肠杆菌平台能够利用含有非生物 Ir-卟啉辅因子的 ArM 进行定向进化活动,涉及生成 4000 多个突变体,以开发对映选择性插入,将简单的无环卡宾从重氮酯插入到N的 N−H 键中-甲基苯胺,在现有酶系统催化下形成对映选择性差的产物。
