== 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.


==Function==
Crystal structure of NS-134 in complex with bovine cathepsin B: a two-headed epoxysuccinyl inhibitor extends along the entire active-site cleft.,Stern I, Schaschke N, Moroder L, Turk D Biochem J. 2004 Jul 15;381(Pt 2):511-7. PMID:15084146<ref>PMID:15084146</ref>
[[http://www.uniprot.org/uniprot/CATB_BOVIN CATB_BOVIN]] Thiol protease which is believed to participate in intracellular degradation and turnover of proteins. Has also been implicated in tumor invasion and metastasis.
