  DOI：10.1039/d1cc04542c

  日期：——

  A carbonyl reductase variant, SmCRM5, from Serratia marcescens was obtained through structure-guided directed evolution. The variant showed improved specific activity (U mg−1) towards most of the 16 tested substrates and gave high stereoselectivities of up to 99% in the asymmetric synthesis of 13 γ-/δ-lactones. In particular, SmCRM5 showed a 13.8-fold higher specific activity towards the model substrate

  来自粘质沙雷氏菌的羰基还原酶变体Sm CR M5是通过结构引导的定向进化获得的。该变体对 16 种测试底物中的大多数表现出改善的比活性 (U mg -1 )，并在 13 种 γ-/δ-内酯的不对称合成中提供高达 99% 的高立体选择性。特别是，SmCR M5对模型底物（即5-氧代癸酸）的比活性高出 13.8 倍，并在 99% ee 中产生 ( R )-δ-癸内酯，时空产率 (STY) 为 301 g L -1 d -1. 六种δ-内酯的高收率和高对映体纯度的制备表明这些高附加值化学品的生物催化合成是可行的，为贵金属催化提供了一种具有成本效益的绿色替代品。
