The crystal structure of the inhibitor NS-134 in complex with bovine cathepsin B reveals that functional groups attached to both sides of the epoxysuccinyl reactive group bind to the part of active-site cleft as predicted. The -Leu-Pro-OH side binds to the primed binding sites interacting with the His110 and His111 residues with its C-terminal carboxy group, whereas the -Leu-Gly-Meu (-Leu-Gly-Gly-OMe) part (Meu, methoxycarbonylmethyl) binds along the non-primed binding sites ...
