After their success using cyanide to drive other chemical reactions, Krishnamurthy and his colleagues suspected that cyanide, even without enzymes, might also help turn α-keto acids into amino acids.

The key reactions in cell metabolism are catalyzed by enzymes, ... This 3-D arrangement of amino acids optimized to catalyze peptide bond hydrolysis has clearly developed at least twice in ...

Their study published in Life used computer simulations (Fig. 2, lower) to clarify why the amino acid L-alanine was preferred over D-alanine during primordial RNA aminoacylation reactions, without ...
