Enantioselective Biohalogenation of Spiro-Epoxyoxindoles Enabled by Engineered Halohydrin Dehalogenases.
We herein describe a biocatalytic halogenation approach that harnesses the reverse dehalogenation reaction of halohydrin dehalogenases. Through the integration of enzyme screening and structure-guided protein engineering, a double mutant of HheC (T134S/W139M) was created for the enantioselective halogenation of spiro-e...
