Crystallization and Preliminary Diffraction Studies of Porcine Pancreatic Elastase in Complex with a Novel Inhibitor
Abstract: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 Å. Crystals belong to the orthorhombic space group P212121, with unit cell parameters a = 50.25 Å, b = 57.94 Å and c = 74.69 Å. PPE is often used as model for drug target, due to its structural homology with the important therapeutic target human leukocyte elastase (HLE). Elastase is a serine protease that belongs to the chymotrypsin family, which has the ability to degrade elastin, an important component in connective tissues. Excessive elastin proteolysis leads to a number of pathological diseases.

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
