Why life encodes specific proteinogenic aminoacids remains an unsolved problem, but a non-enzymatic synthesis that recapitulates biology’s universal strategy of stepwise N-to-C terminal peptide growth may hold the key to this selection. Lysine is an important proteinogenic aminoacid that, despite its essential structural, catalytic, and functional roles in biochemistry, has widely been assumed to
