Directed evolution: Two strategies regarding the application of triple‐code saturation mutagenesis (TCSM) at multiresidue sites of the T. brockii alcohol dehydrogenase (TbSADH) by using distinct reduced amino‐acid alphabets are compared. By using prochiral tetrahydrofuran‐3‐one, highly R‐ and S‐selective variants are obtained with minimal screening. The origin of stereoselectivity is provided by molecular dynamics simulations.

定向进化中的方法学发展：应用三码饱和诱变时探索选择

定向进化：关于三重码饱和诱变（TCSM）的在所述的多残留部位应用的两种策略布氏热厌氧杆菌醇脱氢酶（TbSADH）通过使用不同的减小的氨基酸字母进行比较。通过使用前手性四氢呋喃-3-酮，只需很少的筛选即可获得高度R和S选择性的变体。立体选择性的起源是由分子动力学模拟提供的。
