  • Title: Purification and characterization of the elastase-like enzyme of the bovine granulocyte.
    Author: Marossy K, Hauck M, Elödi P.
    Journal: Biochim Biophys Acta; 1980 Sep 09; 615(1):237-45. PubMed ID: 6903450.
    Abstract:
    The extracts of granules isolated from bovine granulocytes show elastase- and chymotrypsin-like activities, as detected with specific synthetic substrates. Extraction of these enzymes depends upon salt concentration. In the course of the present studies a 21-fold purification of the elastase-like enzyme was achieved on a (Ala)3-CH-Sepharose 4B gel. The molecular weight of the enzyme is 33 000, as determined by gel electrophoresis in the presence of sodium dodecyl sulfate. The elastase-like activity is inhibited by phenylmethylsulfonyl fluoride, soybean trypsin inhibitor, basic pancreatic inhibitor and by heparin at different rates. Elastatinal inhibits the enzyme competitively (Ki = 80 microM). The cytosol of bovine granulocytes contains a protein which strongly inhibits the elastase-like enzyme of the bovine granulocyte (Ki = 0.4 nM) as well as porcine pancreatic elastase (Ki = 11 nM).
