Story summary

Gustavo Caetano-Anollés of the University of Illinois Urbana-Champaign leads a study on dipeptides and early protein evolution.
Researchers analyzed 4.3 billion dipeptides across 1,561 proteomes to map primitive features; published in Journal of Molecular Biology.
Dipeptide patterns align with the genetic code's evolution and support a two-phase amino acid specificity model.
