Snake venom proteinases as tools in hemostasis studies: structure-function relationship of a plasminogen activator purified from Trimeresurus stejnegeri venom.

Snake venom serine proteinases affect many steps of the blood coagulation cascade. Each of them usually acts selectively on one coagulation factor. They are therefore potentially useful components to study the mechanisms of action, the regulation and the structure-function relationships of human serine proteinase coagulation factors. This strategy is illustrated for a plasminogen activator purified from Trimeresurus stejnegeri venom. Copyright 2002 S. Karger AG, Basel
