[chemrxiv.org] Decades of origin-of-life research have uncovered hundreds of prebiotically plausible reactions across hydrothermal, surface, and biochemical environments, yet this knowledge remains fragmented across chemistry, geochemistry, and astrobiology. Here we […]

Deep-time Consistency In Proteome Elemental Composition Across Cellular And Viral Life
Proteins are constructed from a limited alphabet of ~20 amino acids, yet the origins and selection of this specific alphabet are unresolved.

Minimal Amino Acid Alphabet for Protein Design
Proteins are built from 20 canonical amino acids. It is interesting to explore whether proteins can be formed from significantly reduced amino acid alphabets.
