== Publication Abstract from PubMed ==
We report the discovery of an unusual halohydrin dehalogenase, HHDHamb, that can work under relative low acidic conditions and extremely low temperatures for the bio-nitration of epoxides using nitrite as a nitrating agent. The bio-nitration strategy exhibits high chemo-, regio-, and enantioselectivity, catalyzing the kinetic resolution of various epoxides to enantiopure beta -nitroalcohols with nitro-bearing stereocenters in up to 41% isolated yield and &gt;99% enantiomeric excess ( ee ). Additionally, the bio-nitration method displays a high reaction efficiency and can be performed on a gram scale. We also solved the crystal structure of HHDHamb to understand the possible structural determinants of chemoselectivity control in the bio-nitration reaction.
