Mechanism and Origin of Stereoselectivity of Halohydrin Dehalogenase-Catalyzed Ring-Expansion Reaction of Spiro-Epoxides.
The detailed mechanism of halohydrin dehalogenase (HHDH)-catalyzed ring-expansion reaction between spiro-epoxides and the nucleophile OCN- to form spiro-oxazolidinones was investigated using molecular docking, molecular dynamics (MD) simulations, and quantum mechanics/molecular mechanics (QM/MM) calculations.
