Amino acid sequences of two anticoagulant serine fibrinogenases - alpha- and beta-fibrinogenase (VLAF and VLBF) from Vipera lebetina venom have been deduced from the cDNA sequences encoding the enzymes. The mature protein sequences of 234 amino acids (VLAF) and 233 amino acids (VLBF) exhibit significant similarity with other snake venom serine proteinases. Both enzymes contain the catalytic tri...

The venoms from central Asian snakes (Echis carinatus, Echis multisquamatus, Vipera ursini, Vipera lebetina, Agkistrodon halys halys and Naja naja oxiana) contain several enzymes with amidolytic- and procoagulant activity. We have characterized the activities and the mol. wts of the venom enzymes that are able to convert a number of commercially available chromogenic substrates for activated co...
