Crystallization and preliminary diffraction studies of porcine pancreatic elastase in complex with a novel inhibitor.
Porcine pancreatic elastase (PPE) was crystallized in complex with a novel inhibitor at pH 5 and X-ray diffraction data were collected at a synchrotron source to 1.66 A. Crystals belong to the orthorhombic space group P2(1)2(1)2(1), with unit cell parameters a = 50.25 A, b = 57.94 A and c = 74.69 A. PPE is often used as model for drug target, due to its structural homology with the important th...
متن کاملPrimary structure of human neutrophil elastase.
The complete amino acid sequence of human neutrophil elastase has been determined. The protein consists of 218 amino acid residues, contains two asparagine-linked carbohydrate side chains, and is joined together by four disulfide bonds. Comparison of the sequence to other serine proteinases indicates only moderate homology with porcine pancreatic elastase (43.0%) or neutrophil cathepsin G (37.2...
متن کاملStructure of the human neutrophil elastase gene.
The gene for human neutrophil elastase (NE), a powerful serine protease carried by blood neutrophils and capable of destroying most connective tissue proteins, was cloned from a genomic DNA library of a normal individual. The NE gene consists of 5 exons and 4 introns included in a single copy 4-kilobase segment of chromosome 11 at q14. The coding exons of the NE gene predict a primary translati...
متن کاملCrystal structures of the complex of porcine pancreatic elastase with two valine-derived benzoxazinone inhibitors.
The crystal structures of porcine pancreatic elastase complexed to two similar benzoxazinone inhibitors are reported to 2.09 A and 1.76 A resolution, and refined to conventional R factors of 0.153 and 0.172.
متن کاملComplex of human neutrophil elastase with 1/2SLPI
SLPI (secretory leukocyte protease inhibitor) is a 107-residue non-glycosylated protease inhibitor, which inhibits a wide range of serine proteases, trypsin, chymotrypsin, neutrophil elastase, chymase and cathepsin G. X-ray crystallographic analyses have shown that SLPI comprises two separate domains of similar architecture [Grütter, Fendrich, Huber & Bode (1988), EMBO J. 7, 345-351] and the C-...
