我们已经证明,从头设计的多肽在铜存在下自组装,以产生能够在氧气存在下氧化二甲氧基苯酚的超分子组装。超分子组装的形成,类似于蛋白质折叠,对于高效催化至关重要,因为具有相同官能团但缺乏自组装能力的多肽不能催化底物氧化。我们很容易地发现了强大而高效的氧活化催化剂,这表明这些类病毒组装可能在酶功能的进化中起到了中介作用,并为开发新的催化剂纳米材料开辟了道路。从头开始设计了在铜存在下自组装的多肽,以创建催化二甲氧基苯酚被氧气氧化的超分子组件。
We have shown that de novo designed peptides self-assemble in the presence of copper to create supramolecular assemblies capable of oxidation of dimethoxyphenol in the presence of dioxygen. Formation of the supramolecular assembly, akin to a protein fold, is critical for productive catalysis as the peptides possessing the same functional groups, but lacking the ability to self-assemble do not catalyze substrate oxidation. The ease with which we have discovered robust and productive oxygen activation catalysts suggests that these prion-like assemblies might have served as intermediates in evolution of enzymatic function and opens the path for development of new catalyst nanomaterials. De novo designed peptides self-assemble in the presence of copper to create supramolecular assemblies that catalyze oxidation of dimethoxyphenol by dioxygen.
