Dissipative self-assembly processes in nature rely on chemical fuels that activate proteins for assembly through the formation of a noncovalent complex. The catalytic activity of the assemblies causes fuel degradation, resulting in the formation of an assembly in a high-energy, out-of-equilibrium state. Herein, we apply this concept to a synthetic system and demonstrate that a substrate can induce the formation of vesicular assemblies, which act as cooperative catalysts for cleavage of the same substrate.
自然界中的耗散自组装过程依赖于化学燃料,这些燃料通过形成非共价复合物来激活蛋白质进行组装。组装体的催化活性导致燃料降解,从而形成高能、非平衡状态的组装体。在此,我们将这一概念应用于一个合成体系,并证明了底物可以诱导囊泡组装体的形成,这些组装体作为同种底物裂解的协同催化剂。
