Inhibitors of trypsin and alpha-chymotrypsin with Mr of about 7000 Da and isoelectric points of greater than 10 and 9.9, respectively, were isolated from the venom of the common viper Vipera berus berus, using gel filtration and ion exchange chromatography. The inhibitor I prefers alpha-chymotrypsin (Ki = 4.6 X 10(-10) M) for the formation of an(More)
Two serine hydrolases have been separated from the proteolytic complex of the venom of Levantine viper, Vipera lebetina turanica. The enzyme with mol. weight of 50,000 +/- 5,000, pH-optimum of 8.5 and isoelectric point in the range of 5.6--6.6 had proteolytic activity against casein and hydrolyzed benzoyl-arginine p-nitroanilide. The other enzyme with mol.(More)
