Fooling with substrate recognition: Guanidinophenyl (OGp) esters were utilized as potential substrate mimetics for papain‐induced dipeptide synthesis under aqueous conditions. Surprisingly, modeling studies instead revealed unprecedented enzyme‐specific activation, applicable to nearly all amino acids.

A set of new activating esters was evaluated in an enzymatic, papain‐catalyzed approach to synthesizing dipeptides under aqueous conditions. In particular, benzyl and dimethylaminophenyl esters yielded the corresponding dipeptides in several instances in high yields and with relatively small levels of hydrolysis. These results were also interpreted by computational docking analysis.
