~~== Publication Abstract from PubMed ==~~

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. Comparison with the propeptide structures of cathepsins revealed that the binding of the latter part is least similar to the procathepsin B structure; this result, together with the two-residue shift in positioning of the Leu-Gly-Gly part, suggests that the propeptide structures of the cognate enzymes may not be the best starting point for the design of reverse binding inhibitors.
