To develop a comprehensive ‘cells-first’ approach to the origin of life, we propose that protocells form spontaneously and that the fission and fusion of these protocells drives the dynamics of their evolution. The fitness criterion for this evolution is taken to be the the stability (conservation) of domains in the protocellular membrane as determined by non-covalent molecular associations between the amphiphiles of the membrane and a subset of the macromolecules in the protocell. In the… 

A recursive vesicle-based model protocell with a primitive model cell cycle

It is shown that newborn daughter GVs can be restored to the status of their parental GVs by pH-induced vesicular fusion ofdaughter GVs with conveyer GVs filled with depleted substrates.

Questions for cell cyclists

The readiness with which this Min hypothesis has been embraced may herald a serious interest in the value of theory and in the possible relevance of concepts found in physics and physical chemistry, although it may of course simply reflect a lack of critical interest.

How did Metabolism and Genetic Replication Get Married?

It is argued that the functional assemblies of macromolecules that constitute hyperstructures in modern bacteria are the descendants of composomes and that interactions at the hyperstructure level control the cell cycle.

A relationship between membrane properties forms the basis of a selectivity mechanism for vesicle self-reproduction

It is demonstrated that vesicle self-reproduction can occur only at selected values of vesicles properties, and suggested that at times much longer than Td the number ofvesicles with their properties near the “edge” in the system parameter space defined by the minimum value of the product TdLpκC04, will greatly exceed thenumber of any other vesicular numbers.

Molecular complementarity between simple, universal molecules and ions limited phenotype space in the precursors of cells

The hypothesis that the direct interactions between PHB, PolyP, polyamines and lipids – modulated by calcium – played a central role in solving the fundamental problems faced by early and modern cells is explored.

Systems protobiology: origin of life in lipid catalytic networks

The invigorated GARD scrutiny presented in this review enhances the validity of autocatalytic sets as a bona fide early evolution scenario and provides essential infrastructure for a paradigm shift towards a systems protobiology view of life's origin.

The Lipid World

A Lipid World model for the origin of life is proposed, which combines the potential chemical activities of lipids and other amphiphiles, with their capacity to undergospontaneous self-organization into supramolecular structures such as micelles and bilayers.

Lack of evolvability in self-sustaining autocatalytic networks constraints metabolism-first scenarios for the origin of life

It is demonstrated here that replication of compositional information is so inaccurate that fitter compositional genomes cannot be maintained by selection and the system lacks evolvability, cautions against metabolism-first theories of the origin of life, although ancient metabolic systems could have provided a stable habitat within which polymer replicators later evolved.



The origin of cells: a symbiosis between genes, catalysts, and membranes.

It is argued that the obcell was the substratum for the origin of DNA replication; DNA segregation by the growth and division of the peptidoglycan murein; periplasmic solute-binding proteins; bioenergetics; and facilitated diffusion of nutrients across membranes, and that it played the major role in the replacement of ribozymes by protein catalysts.

This model implies that proton translocation in a closed-membrane system preceded photochemical or electron transport mechanisms and that chemically transferable metabolic energy was needed at a much earlier stage in the development of life than has usually been assumed.

The chemical logic of a minimum protocell

This work discusses an alternative system consisting of replicating membrane vesicles, which it defines as minimum protocells, that consist of vesicular bilayer membranes that self-assemble from relatively rare organic amphiphiles present in the prebiotic environment.

A principle of natural self-organization

An analysis of experimental data regarding RNA and DNA replication at various levels of organization reveals, that a sufficient amount of information for the build up of a translation machinery can be gained only via integration of several different replicative units (or reproductive cycles) through functional linkages.

Autocatalytic gene expression occurs via transertion and membrane domain formation and underlies differentiation in bacteria: a model.

When bacteria contain two chromosomes, two or more copies of the same gene are present in the same cytoplasm and, if these copies are subject to negative regulation in trans and positive

Hypothesis: transcriptional sensing and membrane‐domain formation initiate chromosome replication in Escherichia coli

A mechanism for coupling the rate of initiation of replication (and so cell division) to the rates of mass increase is essential if cells are not to change progressively in size with each generation.

Hypothesis: chromosome separation in Escherichia coli involves autocatalytic gene expression, transertion and membrane‐domain formation

It is proposed that differential gene expression occurs during DNA replication in Escherichia coli and that the partitioning relationship between chromosome age and cell age arises because the poles of cells have a proteolipid composition that favours transertion from one nucleoid rather than from the other.

The model proposed here, the exemption from methylation is attributed to the phospholipid preferences of proteins binding hemi-methylated origins to membrane; these proteins associate with unsaturated phosphatidylethanolamine which forms structures with small radii of curvature which makes it inaccessible to cytoplasmic enzymes such as Dam methyltransferase.

A self-replicating peptide

It is shown that a 32-residue α-helical peptide based on the leucine-zipper domain of the yeast transcription factor GCN4 can act autocatalytically in templating its own synthesis by accelerating the thioester-promoted amide-bond condensation of 15- and 17-residine fragments in neutral, dilute aqueous solutions.
