摘要

肽折叠体具有可预测和可控制的三维结构，是一类有利于开发功能分子的化合物。其中最具挑战性的应用之一是构建类似酶的催化剂。在这里，我们介绍了如何优化由两个 9/12/9/10 螺旋组成的多肽折叠体，使其具有顺式-2-氨基环戊烷羧酸残基的逆醛醇活性。通过对螺旋手性、螺旋间连接刚性和活性位点结构的修改，产生了高活性的逆醛酸酶模拟物。核磁共振测量证实了活性位点残基的假定排列。

Optimization of peptide foldamer-based artificial retro-aldolase†

Due to their predictable and controllable three-dimensional structure, peptide foldamers constitute a class of compounds beneficial for developing functional molecules. One of the most challenging applications is the construction of enzyme-like catalysts. Here, we describe the optimization of peptide foldamers composed of two 9/12/9/10-helices incorporating cis-2-aminocyclopentanecarboxylic acid residues toward retro-aldol activity. Modifications related to helix handedness, interhelical linker rigidity, and active site construction led to highly active retro-aldolase mimetics. NMR measurements confirmed the assumed arrangement of active site residues.
