本综述重点关注具有合成有用特性的醛缩酶的定向进化。定向进化已被用来解决与使用野生型醛缩酶作为合成有机化学催化剂相关的许多限制。描述了具有修饰或扩展的底物库的醛缩酶的产生。特别强调具有修饰的立体化学性质的醛缩酶的定向进化:此类酶可以成为生物活性小分子的立体选择性合成中有用的催化剂。该评论还描述了定向进化可以提供的一些对机械酶学的基本见解。
This review focuses on the directed evolution of aldolases with synthetically useful properties. Directed evolution has been used to address a number of limitations associated with the use of wild-type aldolases as catalysts in synthetic organic chemistry. The generation of aldolase enzymes with a modified or expanded substrate repertoire is described. Particular emphasis is placed on the directed evolution of aldolases with modified stereochemical properties: such enzymes can be useful catalysts in the stereoselective synthesis of biologically active small molecules. The review also describes some of the fundamental insights into mechanistic enzymology that directed evolution can provide.
