Enzyme-Instructed Self-Assembly for Cellular Supramolecular Chemistry.

Area of Science:

• Supramolecular Chemistry
• Chemical Biology
• Nanotechnology

Background:

• Enzyme-instructed self-assembly (EISA) leverages endogenous enzymatic activity for controlled nanostructure formation.
• Unlike pH, redox, or light triggers, EISA utilizes enzyme localization and kinetics for precise spatiotemporal control.
• Existing reviews cover EISA mechanisms and applications, but a conceptual framework for supramolecular chemical biology is needed.

Purpose of the Study:

• To position EISA as a framework for supramolecular chemical biology.
• To emphasize EISA's role in mimicking protein assemblies and bridging molecular design with cellular function.
• To explore EISA's potential beyond alkaline phosphatases to multi-enzyme networks for advanced applications.

Main Methods:

• Conceptual analysis and perspective on EISA's capabilities.
• Discussion of EISA's programmability for conformational and morphological switching.
• Exploration of in situ formation of supramolecular architectures within cellular environments.

Main Results:

• EISA enables programmable switching and creation of growth factor-mimicking assemblies.
• Artificial supramolecular architectures can be formed in situ inside or around cells.
• EISA acts as a catalytic strategy for constructing functional supramolecular systems in vivo.

Conclusions:

• EISA offers a new direction for integrating enzymatic control with nanoscale self-organization in cellular supramolecular chemistry.
• Generalizing EISA to programmable multi-enzyme networks advances adaptive biomaterials, programmable therapeutics, and synthetic cellular machines.
• EISA provides precise, context-dependent control over nanostructure formation within biological systems.
