Despite recent advances in molecular mechanism of cell biology, a large blind spot still exists between non-living matter and the emergence of life which cannot be filled by biology alone. The quest to comprehend the cell origin inspires the construction of synthetic analogs (protocells) to mimic their life-like functionality and structural complexity. Among all kinds, coacervates formed by liquid-liquid phase separation featured by their dynamic structure, molecularly crowded interior and molecular sequestration capability, have been regarded as a protocell model for exploring the origin of life. Their biological counterparts in natural cells are also found to facilitate subcellular organization and spatiotemporal regulation of biological molecules. In this tutorial review, we summarize the recent progress on engineering coacervate protocells to potentially reproduce the function and structure of primitive life by multiphase organization, membranization and structural hybridization. Routes to high-ordered protocellular system comprising spatially arranged coacervates, as well as to the construction of tissue-like structures are also described. Finally, we deduce some perspectives of coacervate engineering in the direction of the emergence of life, from molecular scale to the emergence of integrated multicellular system.</p></div>","PeriodicalId":101187,"journal":{"name":"Supramolecular Materials","volume":"1 ","pages":"Article 100019"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667240522000125/pdfft?md5=900a8735b5af9a45e2c13e35e9e59f82&pid=1-s2.0-S2667240522000125-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72280167","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 modified oligohistidine materials are able to catalyze H<sub>2</sub>O<sub>2</sub> reduction reactions efficiently through the formation of reactive ternary complex intermediates, similar to the mechanism to the unmodified oligohistdine, but the catalytic efficiency is over one order of magnitude higher. Moreover, the catalyst can be switched between inactive and active state without loss of activity for more than ten cycles of heating/cooling treatments, and showed selective oxidation of benzidine substrates over phenolic substrates.

However, it remains challenging to study the strength of cation-π interactions at the single-molecule level. Here, we engineer a recombinant chimeric polyprotein containing the mussel foot proteins-5 (MFP5) and a finger print domain GB1 to unambiguiously quantify the strength of cation-π interactions using atomic force microscopy (AFM)-based single-molecule force spectroscopy. Our results show that the formation of intermolecular cation-π interactions can be triggered at elevated salt concentrations, consistent with previous ensemble studies. Individual cation-π interaction ruptures at about 70 pN at a pulling speed of 1.6 μm s<sup>−1</sup>, comparable to the strength of other non-covalent interactions. The strength of cation-π interactions is weakly dependent on pH, which is in stark contrast with the hydrogen bonding and charge-charge interactions. Moreover, we find that the position of the cation-π bonds are formed randomly along the polyprotein chains. The propensity of forming long range cation-π interactions increases considerably when increasing the pH from 4 to 8, presumably due to the neutralization of the positive changes of MFP5. Our study directly quantifies the mechanical strength of cation-π bonds in the biological relavent settings and reveals key design parameters that may inspire the design of biomimetic strong underwater adhesives.</p></div>","PeriodicalId":101187,"journal":{"name":"Supramolecular Materials","volume":"1 ","pages":"Article 100005"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667240521000052/pdfft?md5=76b77905bf3d11637b83f0e1cd57cb36&pid=1-s2.0-S2667240521000052-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84334508","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}
