Amino acid N-carboxyanhydrides: activated peptide monomers behaving as phosphate-activating agents in aqueous solution.
The hydrolysis of valine N-carboxyanhydride (NCA) in aqueous phosphate buffers was shown to proceed through nucleophilic catalysis via an aminoacyl phosphate intermediate that displays phosphorylating capabilities through a potentially prebiotic process that simulates modern biochemical metabolic pathways.
