Alkaline thrombin-like serine protease. Has fibrinolytic and fibrinogenolytic but not plasminogenolytic activity. Cleaves fibrinogen chains Aalpha, Bbeta and gamma chains in that order. Cleaves after Arg and Lys residues. Inhibited by PMSF. Not or very weakly inhibited by EDTA, EGTA, beta-mercaptoethanol, benzamidine, aprotinin, iodoacetic acid, pepstatin A and SBTI. Optimum pH is 9.0. Activity is stable from pH 7 to 11. Optimum temperature is 40 degrees Celsius. Activity is stable from 30 to 60 degrees Celsius and. The measured range is 1-?. On the 2D-gel the determined pI of this protein is: 9.2, its MW is: 33.5 kDa. The order of the peptides shown is unknown.
