4.1.2.47 C81L 1.3fold increase in kcat for racemic mandelonitrile Hevea brasiliensis
4.1.2.47 C81L the mutant has high enantioselectivity towards (R)-mandelonitrile with a kcat value 1.3times higher compared to the wild type enzyme Hevea brasiliensis
4.1.2.47 F125T 2.6fold increase in kcat for racemic mandelonitrile, 4.5fold increase in specificity constants (kcat/Km) for racemic mandelonitrile Hevea brasiliensis
