Neutrophil Elastase, Recombinant, Mouse, aa27-265, His-Tag

Neutrophil elastase, also known as polymorphonuclear leukocyte eslastase, is a serine protease that classified as the chymotrypsin family. This protein breaks down elastin, an elastic fiber together with collagen and determines the mechanical properties of connective tissue. The neutrophil form breaks down the outer membrane protein A (OmpA) of E. coli and other Gram-negative bacteria. Also, this protein is inhibited by the acute-phase protein alpha 1-antitrypsin (A1AT), which binds almost irreversibly to the active site of elastase and trypsin. A1AT is normally secreted by the liver cells into the serum. Alpha-1-antitrypsin deficiency (A1AD) leads to uninhibited destruction of elastic fiber by elastase.
