Non-equilibrium self-assembly for living matter-like properties.

Area of Science:

• Systems Chemistry
• Origin of Life Research
• Chemical Biology

Background:

• Life emerged from spatially enclosed biomolecules with metabolism and replication.
• These systems operate far-from-equilibrium, a key characteristic of living matter.
• Understanding this emergence is crucial for synthetic biology and origins of life studies.

Purpose of the Study:

• To review the synthetic integration of metabolic and replicative properties.
• To explore the construction of chemical-based evolving systems with life-like properties.
• To map discoveries on integrating reaction networks, self-reproduction, and compartmentalization under non-equilibrium conditions.

Main Methods:

• Deconvolution of reaction networks and transient compartmentalization events.
• Analysis of self-reproducing systems sustained under non-equilibrium conditions.
• Review of emerging strategies for minimal metabolic cycles.

Main Results:

• Integration of metabolic and replicative functions in confined, non-equilibrium systems is achievable.
• Transient compartmentalization plays a role in the emergence of self-reproducing systems.
• Minimal metabolic cycles offer pathways to understanding chemical evolution.

Conclusions:

• Synthetic integration of life's core properties is a monumental systems chemistry endeavor.
• Challenges remain in molecular diversity, information transfer, adaptation, and selection for open-ended evolution.
• Emerging strategies advance our understanding of the chemical emergence of Earth's biosphere.
