the C-terminal amide groups in N-protected peptides could be efficiently replaced by ester groups via kinetically-controlled papain-catalyzed acyl transfer reactions in aqueous methanol. The specificity of papain was substantially shifted towards the cleavage of C-terminal amide bond in dipeptide substrates by methanol, thus suppressing undesired peptidebond cleavage during esterification.
