Abstract: Blood serine protease inhibitors are becoming better understood and increasingly applied in blood clotting, cancer and other diseases. Reptiles are suitable models for blood coagulation and related processes, moreover, caiman is a good comparative model of a non-poisonous reptile. Recently, we reported the purification of a kininogen, the presence of proteases involved in blood clotting, and a serine protease inhibitor in Caiman crocodilus yacare plasma. in this paper, we described the partial sequence of an inhibitor (CcTI). the inhibitor is an 80-kDa protein, and it inactivates trypsin and chymotrypsin the hydrolysis of specific chromogenic substrates and in the degradation of gelatin. the inhibitor is member of Kazal-type inhibitor family and consists of several domains, its putative reactive: site is Arg-His.
