[Preparative isolation of terrilytin components and study of their enzymatic properties]

By ion-exchange chromatography the composition of the fibrinolytic enzyme from Aspergillus terricola-terrilytine-was studied. The preparation contained five components that differed in their substrate specificity. Three of the components and proteolytic and fibrinolytic activities. The isolated fractions were examined with respect to their pH stability, pH optima (casein, hemoglobin and fibrin used as substrates), fibrinolytic and fibrinohenolytic activities.
