Highly dynamic and complex systems of microtubules undergo a substrate‐induced change of conformation that leads to polymerization. Owing to the augmented catalytic potential at the polymerized state, rapid hydrolysis of the substrate is observed, leading to catastrophe, thus realizing the out‐of‐equilibrium state. A simple synthetic mimic of these dynamic natural systems is presented, where similar substrate induced conformational change is observed and a transient helical morphology is accessed. Further, augmented catalytic potential of these helical nanostructures leads to rapid hydrolysis of the substrate providing negative feedback on the stability of the nanostructures and realization of an out‐of‐equilibrium state. This simple system, made from amino acid functionalized lipids, demonstrates a substrate‐induced self‐assembled state, where the fuel‐to‐waste conversion leads to the temporal presence of helical nanostructures. 相似文献

A photoresponsive system where structure formation is coupled to catalytic activity is presented. The observed catalytic activity is reliant on intermolecular cooperative effects that are present when amphiphiles assemble into vesicular structures. Photoresponsive units within the amphiphilic pre‐catalysts allow for switching between assembled and disassembled states, thereby modulating the catalytic activity. The ability to reversibly form cooperative catalysts within a dynamic self‐assembled system represents a conceptually new tool for the design of complex artificial systems in water. 相似文献
