Current Ideas about Prebiological Compartmentalization

open access: yesLife, 2015
Contemporary biological cells are highly sophisticated dynamic compartment systems which separate an internal volume from the external medium through a boundary, which controls, in complex ways, the exchange of matter and energy between the cell’s ...

Fatty Acid-Based Coacervates as a Membrane-free Protocell Model

open access: yes, 2022
Membrane-less scenarios that involve liquid–liquid phase separation (coacervation) provide clues for how protocells might emerge. Here, we report a versatile approach to construct coacervates by mixing fatty acid with biomolecule dopamine as the ...

Compartmentalization and Cell Division through Molecular Discreteness and Crowding in a Catalytic Reaction Network

open access: yesLife, 2014
Explanation of the emergence of primitive cellular structures from a set of chemical reactions is necessary to unveil the origin of life and to experimentally synthesize protocells.

Antagonistic chemical coupling in self-reconfigurable host–guest protocells

open access: yesNature Communications, 2018
Multi-compartmentalised soft micro-systems are used as models of synthetic protocells. Here, the authors developed nested host–guest protocell constructs capable of self-reconfiguration in response to changes in pH generated by antagonistic modes of ...

Concepts of a synthetic minimal cell: Information molecules, metabolic pathways, and vesicle reproduction

open access: yesBiophysics and Physicobiology
How do the living systems emerge from non-living molecular assemblies? What physical and chemical principles supported the process? To address these questions, a promising strategy is to artificially reconstruct living cells in a bottom-up way. Recently,

Synchronization phenomena in non linear protocell model

open access: yes, 2009
In this paper we study general protocell models aiming to un-derstand the synchronization phenomenon of genetic material and containerproductions, a necessary condition to ensure sustainable growth in protocellsand eventually leading to Darwinian ...

A Model Protometabolic Pathway across Protocell Membranes Assisted by Photocatalytic Minerals

open access: yes, 2019
Protocell analogs (lipid vesicles) to modern cell membranes have been postulated as compartments that may have been involved in primordial metabolism during the transition from geochemistry to biochemistry on early Earth. The transduction of light energy

Protocol for building synthetic protocell membranes that sense redox using synthetic phospholipids and natural lipids

open access: yesSTAR Protocols
Summary: Sensing is a critical function of artificial cells; however, this is challenging to realize using bottom-up approaches. Here, we present a protocol for building protocell membranes that sense cues important for redox biochemistry and signaling ...

Preliminary steps toward artificial protocell computation [PDF]

open access: yes, 2007
Protocells are hypothesised as a transitional phase in the origin of life, prior to the evolution of fully functional prokaryotic cells. The work reported here is being done in the context of the PACE project, which is investigating the fabrication of ...
