摘要:The present invention provides engineered polypeptides that are useful for the asymmetric synthesis of β-hydroxy-α-amino acids under industrial-relevant conditions. The engineered polypeptides disclosed in this invention were developed through directed evolution based on the ability of catalytic synthesis of (2S, 3R)-2-amino-3-hydroxy-3-(4-nitrophenyl) propanoic acid. The present disclosure also provides polynucleotides encoding engineered polypeptides, host cells capable of expressing engineered polypeptides, and methods of producing β-hydroxy-α-amino acids using engineered polypeptides. Compared to other processes of preparation, the use of the engineered polypeptides of the present invention for the preparation of β-hydroxy-α-amino acids results in high purity of the desired stereoisomers, mild reaction conditions, low pollution and low energy consumption. So, it has good industrial application prospects.
