and signal transduction. However, the intentional incorporation of frustrated noncovalent interactions has not been explored as a design element in the field of dynamic foldamers. Here, we report the design, synthesis, characterization, and molecular dynamics simulations of the first dynamic water-soluble foldamer that, in response to a stimulus, exploits relief of frustration in its noncovalent network
人们认为,受阻或非最佳相互作用对于蛋白质表现出变构、构象信号传导和信号转导等响应行为的能力至关重要。然而,有意纳入受挫的非共价相互作用尚未被探索作为动态折叠器领域的设计元素。在这里,我们报告了第一个动态水溶性折叠体的设计、合成、表征和分子动力学模拟,该折叠体响应刺激,利用其非共价网络中的挫败感的缓解,从褶皱结构重新排列为插层柱状结构。因此,挫败感的缓解为结构重组提供了强劲的动力。这项工作代表了以前未探索过的刺激响应系统开发的设计元素,该系统在材料化学、合成生物学和分子机器方面具有潜在的应用前景。
