[Thrombin-like serine proteases in Cerasted venoms (Cerasted cerastes and Cerastes vipera)].

Cerastes cerastes and Cerastes vipera snake venoms are rich of thrombin-like, serine-protease polypeptides. Many proteins have been isolated, purified and characterized from these vipers. These proteins act in various way on blood coagulation pathway and platelet function.
