Bothrojaracin binds to the thrombin precursor, prothrombin. This interaction is calcium-independent and is prevented by heparin, suggesting that it is mediated by exosite 2. Bothrojaracin inhibits platelet activation induced by clot-bound thrombin and slowly dissociates thrombin from the fibrin clots. WebO Scribd é o maior site social de leitura e publicação do mundo.

WebMay 9, 2005 · Bothrojaracin is a snake venom-derived protein that binds to thrombin exosites 1 and 2. Complex formation impairs several exosite-dependent activities of thrombin including fibrinogen cleavage and platelet activation. Bothrojaracin also interacts with proexosite 1 on prothrombin thus decreasing the zymogen activation by the … WebBothrojaracin is a potent and specific alpha-thrombin inhibitor (Kd approximately 0.6 nM) isolated from Bothrops jararaca venom. It binds to both of thrombin's anion-binding exosites (1 and 2), thus inhibiting the ability of the enzyme to act upon several natural macromolecular substrates, such as fibrinogen, platelet receptor, protein C, and factor V. …
