Crystal structure of human caspase-1 in complex with 4-oxo-3-[(6-{[4-(quinoxalin-2-ylamino)-benzoylamino]-methyl}-pyridine-3-carbonyl)-amino]-butyric acidCrystal structure of human caspase-1 in complex with 4-oxo-3-[(6-{[4-(quinoxalin-2-ylamino)-benzoylamino]-methyl}-pyridine-3-carbonyl)-amino]-butyric acid

Structural highlights

1rww is a 2 chain structure. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Activity:Caspase-1, with EC number 3.4.22.36
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

[CASP1_HUMAN] Thiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Can also promote apoptosis.[1] [2]

Publication Abstract from PubMed

Disulfide Tethering was applied to the active site of human caspase-1, resulting in the discovery of a novel, tricyclic molecular fragment that selectively binds in S4. This fragment was developed into a class of potent inhibitors of human caspase-1. Several key analogues determined the optimal distance of the tricycle from the catalytic residues, the relative importance of various features of the tricycle, and the importance of the linker.

Tethering identifies fragment that yields potent inhibitors of human caspase-1.,Fahr BT, O'Brien T, Pham P, Waal ND, Baskaran S, Raimundo BC, Lam JW, Sopko MM, Purkey HE, Romanowski MJ Bioorg Med Chem Lett. 2006 Feb;16(3):559-62. Epub 2005 Nov 4. PMID:16274992[3]
