Abstract

Fibrinolytic and fibrinogenolytic activities of the venoms from the Korean snakes, Agkistrodon caliginosus, nosus, Agkistrodon saxatilis and Agkistrodon blomhoffi brevicaudus were compared by fibrin-plate method and polyacrylamide gel electrophoresis, respectively. The venom from A. blomhoffi brevicaudus showed the highest degree of fibrin(ogen)olytic activity, and a protease with the fibrin(open)olytic activity was purified by p-amino-benzamidine affinity chromatography and DEAE ion-exchange chromatography. The purified enzyme had a molecular weight of 50,800 and a capability to degrade the B$\beta$-chain of fibrinogen preferentially to the $A\alpha$-chain, but not the ${\gamma}$-chain. Fibrinolytic activity of the purified enzyme was approximately 3.8 plasmin unit/mg protein.
