dehalogenase from Agrobacterium radiobacter AD1 (HheC) catalyzes nucleophilic ring opening of epoxides with cyanide and azide. In the case of 2,2-disubstituted epoxides, this reaction proceeds with excellent enantioselectivity (E values up to>200), which gives, by kinetic resolution, access to various enantiopure epoxides and β-substituted tertiary alcohols (ee up to 99 %). Since the enzyme has a broad
