Substrate-Induced Self-Assembly of Cooperative Catalysts

Area of Science:

• Supramolecular Chemistry
• Chemical Systems Biology
• Materials Science

Background:

• Nature utilizes dissipative self-assembly, driven by chemical fuels activating protein complexes.
• These assemblies are catalytically active, degrading fuel and reaching non-equilibrium states.

Purpose of the Study:

• To engineer a synthetic system mimicking natural dissipative self-assembly.
• To demonstrate substrate-induced vesicular assembly and cooperative catalysis.

Main Methods:

• Design of a synthetic system where a substrate initiates noncovalent complex formation.
• Observation of substrate-induced vesicular assembly.
• Characterization of the catalytic activity of the formed assemblies.

Main Results:

• A substrate successfully induced the formation of vesicular assemblies.
• These vesicular assemblies exhibited cooperative catalytic activity.
• The assemblies catalyzed the cleavage of the same substrate that induced their formation.

Conclusions:

• Synthetic dissipative self-assembly is achievable using a substrate-driven approach.
• Vesicular assemblies can function as cooperative catalysts in synthetic systems.
• This work provides a synthetic analogue for energy-dissipating biological self-assembly.
