Enantioselectivity reversal: Candida rugosa lipase (CRL) exhibits unexpected enantioselectivity (i.e., S selectivity, E=58) towards 4‐(tert‐butoxycarbonylamino)butan‐2‐ol. A molecular modeling study suggests that the formation of a hydrogen bond between the Ser450 residue and the carbamate nitrogen atom is essential for the observed selectivity.
对映选择性逆转:皱纹念珠菌脂肪酶(CRL)对4-(叔-丁氧基羰基氨基)丁烷-2-醇显示出出乎意料的对映选择性(S选择性,E = 58)。分子建模研究表明,Ser450残基和氨基甲酸酯氮原子之间形成氢键对于观察到的选择性至关重要。
