PEPTIDES ATTACHED TO THROMBIN: THEIR INFLUENCE ON PROTEOLYSIS.

During the activation of prothrombin at least two peptides are split off the molecule. These peptides become attached to thrombin, changing its proteolytic activity. Depending on the peptide adsorbed the endopeptidase activity of thrombin increases or diminishes. Acidification of thrombin by acetylation of amino groups uncovers the influence of peptides on the properties of thrombin.

Thrombin-E as a fibrinolytic enzyme.

Thrombin-E has been produced in adequate quantity for pharmacological studies. After intravenous infusion in dogs there were no significantchanges in blood pressure, temperature, pulse rate, and respiratory movements. There were drops in platelet and white cell count, and there was an increase in bloodsugar level. Powerful fibrinolytic phenomena wereobserved.
