In the absence of these sophisticated molecular machineries, alternatives were required for primitive protocells to proliferate and disseminate genetic material. Recurring environmental constraints on ancient earth, such as temperature cycles, are considered as prebiotically plausible driving forces capable of shuffling of protocellular contents, thereby boosting compositional complexity. Using confocal fluorescence microscopy, we show that temperature oscillations such as freezing-thawing (FT) cycles promote efficient content mixing between giant unilamellar vesicles (GUVs) as model protocells. We shed light on the underlying exchange mechanism and demonstrate that transient periods of destabilized membranes enable the diffusion of cargo molecules across vesicle membranes. Furthermore, we determine essential parameters, such as membrane composition, and quantify their impact on the lateral transfer efficiency. Our work outlines a simple scenario revolving around inter-protocellular communication environmentally driven by periodic freezing and melting of water.</p>","PeriodicalId":72566,"journal":{"name":"ChemSystemsChem","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/syst.202300008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41402915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reaction mixture, an aqueous solution of chlorate, sulfite and δ-gluconolactone, is contained in a beaker. The blue color suggests that the pH is basic, and the thermometer indicates that the mixture is at room temperature. The clock shows the time at which the reactants have been mixed. The hydrolysis of δ-gluconolactone triggers the acid-autocatalyzed exothermic chlorate-sulfite reaction. As a result, after some time the content of the beaker has become highly acidic (red color) and hot (vapors, and thermometer indicating a higher temperature).

In recent years, bio-inspired synthetic receptors have been developed to bind carbohydrates, with examples of (pseudo)temple-shaped receptors, flexible receptors, and dynamic-covalent/coordinative receptors reported. Certain of these have even demonstrated promising results, for example in binding glucose or exhibiting antiviral and antibiotic function.

Here, we report a carbodiimide-based approach, combined with electrostatic modulation, to instruct π-conjugated peptides to self-assemble and be responsive to thermal disassembly cues upon consumption of the assembly trigger. Quaterthiophene-functionalized peptides are utilized as a model system herein to study the formation of nanostructures at non-equilibrium states. Peptides were designed to have aspartic acid at the termini to allow intramolecular anhydride formation upon adding carbodiimide, which consequentially reduces the electrostatic repulsion and facilitates assembly. We show that the carbodiimide-fueled assembly and subsequent thermally assisted disassembly can be modulated by the net charge of the peptidic monomers, suggesting an assembly mechanism that can be encoded by sequence design.
