SummaryIt is proposed that the first entity capable of adaptive Darwinian evolution consisted of a liposome vesicle formed of (1) abiotically produced phospholipidlike molecules; (2) a very few informational macromolecules; and (3) some abiogenic, lipid-soluble, organic molecule serving as a symporter for phosphate and protons and as a means of high-energy-bond generation. The genetic material had functions that led to the production of phospholipidlike materials (leading to growth and division… 

The first cellular bioenergetic process: Primitive generation of a proton-motive force

The energy-transducing system of the first cellular organism and its precursor was fueled by the oxidation of hydrogen sulfide and ferric sulfide to iron pyrites and two on the outside surface of a vesicle (the cell membrane), with the concomitant reduction of CO or CO2 on the interior.

A Fission-Fusion Origin for Life

It is indicated how domain evolution with the same fitness criterion can potentially give rise to coding and Membrane domains may provide the link between protocells and the RNA/DNA-world.

Vesicle encapsulation of a nonbiological photochemical system capable of reducing NAD(+) to NADH.

It is shown that the encapsulation of TiO2 particles has the potential to provide the basis for an energy transduction system inside vesicles which can be used to drive subsequent chemistry.

Energetically Plausible Model of a Self-Maintaining Protocellular System

The model presented here focuses on the latter, consisting of the combination of kinetic and energetic descriptions of protocellular metabolism, which plays a very crucial role in the maintenance of the cell and the osmotic stability.

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.

Energy Transduction Inside of Amphiphilic Vesicles: Encapsulation of Photochemically Active Semiconducting Particles

It is shown that TiO2 particles, in the ~20 nm size range, can be incorporated into vesicles and retain their photoactivity through the dehydration/rehydration cycles that have been shown to concentrate species inside a vesicle.

Prebiological Membranes and Their Role in the Emergence of Early Cellular Life

This review critically evaluates existing research on prebiotic membranes in terms of their probable origin, composition, energetics, function and evolution and outlines new approaches that can further understanding about how prebiotics membranes might have evolved in response to relevant physicochemical parameters that would have acted as pertinent selection pressures on the early Earth.

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.



Evolution of membrane bioenergetics.

This work proposes that to meet the environmental challenge of volume regulation, primitive cells evolved an ATP-driven proton extrusion system plus a membrane carrier that would exchange external protons with internal Na+.

Membrane Lipids and the Origin of Life

Evidence suggests that the extant Archaebacteria evolved from a common anaerobic ancestral line when the primitive Earth was evolving from anoxidic to oxidic conditions at about 3.7 Aeons ago.

The coupling of wall growth and chromosome replication in Gram-positive rods

A Renovated Replicon Model (RRM) is proposed which leads to accurate segregation of the chromosomes and equipartitioning of cell contents and explains the high precision of the cell division process in dividing the cytoplasm evenly between daughter Cells.

Compartmentalization of self-reproducing machineries: Multiplication of microsystems with self-instructing polymerization of amino acids

It is shown theoretically that a compartmentalized microsystem fixes inside itself only the process with a faster macromolecular multiplication as time passes, even if the catalytic polymerization alone could spontaneously decrease the corresponding reaction rate.

Synthesis of phosphatidylcholine under possible primitive Earth conditions

This work suggests that phosphatidylcholine, which is an essential component of most biological membranes, could have been synthesized on the primitive Earth.

Liposomes from ionic, single-chain amphiphiles.

Membrane permeability to various solutes was determined in part by a new technique which utilized phase-contract microscopy; when impermeable vesciles exclude added solutes such as sucrose, refractive index differences are created between vesicle contents and surrounding medium, so that the vesicles appear bright in the phase microscope.

It is found that the decay of large pH gradients produces a diffusion potential that limits net proton-hydroxide flux and the permeability coefficients calculated from the flux are therefore underestimated and do not reflect intrinsic proton permeability.
