Abstract
Structure-guided re-design of the acceptor binding site of D-fructose-6-phosphate aldolase from E. coli leads to the construction of FSA A129S/A165G double mutant with an activity between 5- to >900-fold higher than that of wild-type towards N-Cbz-aminoaldehyde derivatives.
摘要
结构指导的大肠杆菌 D-果糖-6-磷酸醛缩酶受体结合部位的重新设计导致构建了 FSA A129S/A165G 双突变体，其对 N-Cbz-氨基醛衍生物的活性比野生型高 5 到 >900 倍。
