Abstract/Description: In this opinion article we argue for the following: 1) 10 of the common α-amino acids were likely available in the prebiotic world, produced by a variety of abiotic chemical syntheses; 2) although a highly-restricted set, experimental and theoretical considerations indicates this prebiotic alphabet of α-amino acids contains the requisite chemical information to comprise a foldable set (i.e., foldable polypeptides are possible having a composition only of the prebiotic alphabet); 3) a comparison of the prebiotic alphabet with known proteomes predicts that polypeptides comprised of the prebiotic alphabet would have halophile properties – i.e., folding and solubility would be compatible with high salt. Recent experimental studies support this hypothesis; 4) proteogenesis (the emergence of polypeptides) – a key aspect of abiogenesis (the emergence of life from non-living molecules) – is likely to have occurred within the halophile environment.
