cysteine protease cathepsinB. It was shown that derivatization of the carboxylate on the epoxide ring confers selectivity for cathepsinB over papain only when it is combined to a dipeptidyl moiety with a free negatively charged C-terminal residue. It is proposed that this selectivity reflects interactions with histidine residues on a loop located in the primed subsites of cathepsinB which provides
