An Enantioselective Artificial Metallo-Hydratase
Direct addition of water to alkenes to generate important chiral alcohols as key motif in a variety of natural products still remains a challenge in organic chemistry. Here, we report the first enantioselective artificial metallo-hydratase, based on the transcription factor LmrR, which catalyses the conjugate addition of water to generate chiral β-hydroxy ketones with enantioselectivities up to 84% ee. A mutagenesis study revealed that an aspartic acid and a phenylalanine located in the active site play a key role in achieving efficient catalysis and high enantioselectivities.
