Towards Synthetic Life: Constructing Peptide-based Minimal Catalytic Protocells with Emergent Functionalities

Project description

Catalytic protocells for exploring the emergence of life-like chemistry

One of science’s major unresolved challenges is to explain how life emerges from non-living chemistry by identifying how simple molecules can self-organise into increasingly complex and functional structures. Supported by the Marie Skłodowska-Curie Actions programme, the CAT-PRO project aims to construct catalytic protocells that mimic early cellular functions using peptide-based liquid-liquid phase separation as a scaffold for proto-metabolism. By incorporating cofactors, it tests whether protocells can drive diverse catalytic reactions, including enantioselective transformations, and self-organise dynamically for operation in flow reactors. It also studies communication between protocells and living cells. By revealing how simple chemistry gives rise to life-like behaviour, the project could drive advances in catalysis, synthetic biology and biomedical technologies by revealing how simple chemistry gives rise to life-like behaviour.

Objective

The CAT-PRO (Catalytic Protocells) project focuses on investigating the emergence of complex functionalities from minimal chemical systems to bridge the gap between prebiotic chemistry and the origin of life. The project aims to construct catalytic protocells that mimic primordial cellular functions, utilizing peptide-based liquid-liquid phase separation as a scaffold for proto-metabolism. By incorporating cofactor molecules, the potential of these protocells to perform diverse catalytic transformations, including enantioselective reactions, will be explored. Further, dynamic structural reconfiguration of these protocells will be studied, alongside their integration into flow reactor systems for scalable and sustainable bioprocessing. Additionally, the project seeks to establish reciprocal communication between protocells and living cells, a step towards achieving the goal of engineering a feedback-driven targeted delivery system. This multidisciplinary approach is expected to provide fundamental insights into the origins of life while advancing the frontiers of heterogeneous catalysis, synthetic biology, and nanomedicine.
