Catalytic effects of histidine enantiomers and glycine on the formation of dileucine and dimethionine in the salt-induced peptide formation reaction.
The salt-induced peptide formation (SIPF) reaction takes place readily under mild reaction conditions and proceeds via a copper complex. Its ease of reaction and the universality for prebiotic scenarios add weights to the arguments in favour of the importance of peptide and proteins in the tug of war with the RNA world hypothesis. In addition, the SIPF reaction has a preference for L-form amino acids in dipeptide formation, casting light on the puzzle of biohomochirality, especially for the a...Expand abstract
