			Abstract 
			
				
				                 
				Green pit viper (GPV) is one of the most common species 
				responsible for venomous snakebites in Thailand. Its venom 
				contains numerous proteins, one of which contains the 
				fibrinogen-clotting effect. Fibrinolysis is then activated, 
				causing bleeding from low fibrinogen levels. Identification of 
				these venom components gives us not only deeper insights in the 
				pathogenesis of snakebites, but also potential novel anti-thrombotic 
				agents. A molecular biology approach was utilized. The mRNA was 
				isolated from fresh venom glands of GPV and used to construct a 
				cDNA phage library of venom protein genes. Each clone was 
				recovered and sequenced. After conceptual translation, 4 major 
				families of venom-specific genes were found; 1.) serine 
				proteases, 2.) snake venom metalloproteases-disintegrin, 3.) C 
				lectins, and 4.) phospholipase A2. Full-length clones were 
				obtained using a 5’RACE method. Four novel serine proteases cDNA 
				from GPV have been cloned and characterized. According to the 
				sequence homology comparison, two are fibrinogen-clotting 
				enzymes, which are likely to be the main fibrinogen-clotting 
				effect found in the crude venom. In addition, there is another 
				enzyme that is likely to directly digest fibrinogen (fibrinogenolysis). 
				Furthermore, a new fibrinolytic enzyme (plasminogen activator) 
				from GPV was cloned. Therefore, the hypofibrinogenemia in humans 
				is the combination of the fibrinogen-clotting, 
				fibrinogen-digesting and fibrin clot lysis by the venom. 
				Detailed analysis showed that the animo acid sequences in the 
				loops around the active sites were likely responsible for their 
				differential effects on fibrinogen-fibrin. The recombinant 
				proteins are now produced and will be tested for their 
				potentials to be novel anticoagulants and thrombolytic agents.
