Microscopic Protein Pairs Could Reveal Life’s Origins

Quick Summary

• Researchers at the University of Illinois Urbana-Champaign led a study uncovering the evolutionary roots of the genetic code.
• The study links the genetic code’s origin to dipeptide composition in proteomes (collective proteins in organisms).
• Researchers analyzed 4.3 billion dipeptide sequences across 1,561 organism proteomes, constructing a phylogenetic tree of evolution and tracking amino acid progression.
• They discovered congruence among protein domains, tRNAs, and dipeptides in mapping amino acids’ entry into the genetic code.
• Key findings include synchronous evolution of “dipeptide” and “anti-dipeptide pairs,” suggesting these pairs were encoded on complementary strands early in life’s history.
• Dipeptides played critical roles as structural elements shaping protein folding and function during early evolution alongside RNA-based processes.
• Implications span fields such as synthetic biology and genetic engineering by showcasing biological systems’ resilience while informing modification and design frameworks.
