• Enzymatic Racemization of Amines Catalyzed by Enantiocomplementary ω-Transaminases

  A strategy for the biocatalytic racemization of primary α‐chiral amines was developed by employing a pair of stereocomplementary PLP‐dependent ω‐transaminases. The interconversion of amine enantiomers proceeded through reversible transamination by a prochiral ketone intermediate, either catalyzed by a pair of stereocomplementary ω‐transaminases or by a single enzyme possessing low stereoselectivity

  通过使用一对立体互补的PLP依赖性ω-转氨酶，开发了伯α-手性胺生物催化消旋的策略。胺对映异构体的相互转化是通过前手性酮中间体的可逆转氨作用进行的，该中间体是由一对立体互补的ω-转氨酶或具有低立体选择性的单一酶催化的。为了调节系统，非手性氨基受体的类型和浓度被证明是至关重要的。最后，外消旋可通过两种不同胺的交叉转氨来实现，而无需外部氨基受体。在温和的反应条件下，可以将几种在工业上和工业上很重要的胺酶消旋化。
