摘要:
2,2-Disubstituted-3-hydroxycyclopentanonesare important chiralintermediates for natural products and pharmaceuticals. Through semirationalengineering of a thermostable carbonyl reductase CBCR from Cupriavidus sp. BIS7, a mutant L91C/F93I was obtained.Mutant L91C/F93I showed 4- to 36-fold enhanced activities toward 2-methyl-2-benzyl-1,3-cyclopentanedioneand its analogues, affording the (2R,3R)-stereoisomers with >99% ee and >99% de. Enzyme-substratedocking studies were performed to reveal the molecular basis for theactivity and stereoselectivity improvements.
