Addtional InformationFUNCTION:Inhibits B.lichenoformis subtilisin, B.subtilis subtilisin, bovine pancreatic alpha-chymotrypsin and porcine alpha-chymotrypsin with Ki of 3.92 nM, 5.70 nM, 7.24 nM and 9.35 nM respectively. B.lichenoformis subtilisin is inhibited with a molar ratio of 1:0.87. Also inhibits chymotrypsin-like activities from the digestive tracts of the insect larvae T.molitor, P.interpunctella and H.armigera. Does not inhibit bovine pancreatic trypsin, porcine pancreatic elastase, or human leukocyte elastase.BIOPHYSICOCHEMICAL PROPERTIES:Temperature dependence: Optimum temperature is 25 degrees Celsius when incubation is carried out at pH 7.0-9.0;SUBUNIT:Monomer.MASS SPECTROMETRY:Mass=8126.3; Mass_error=0.5; Method=Electrospray; Range=13-84; Source=PubMed:12675523;SIMILARITY:Belongs to the protease inhibitor I13 (potato type I serine protease inhibitor) family.
