Abstract
When Glu-plasminogen was activated by streptokinase (SK), the presence of early degradation products of fibrinogen (FgDP) enhanced the rate of activation. When various fragments of FgDP were fractionated, FgDP-Y and E fragments had a potentiating activity while D fragment did not. When Glu-plasminogen was activated by urokinase (UK), the activation rate was enhanced by every fragment of FgDPs, i.e. X, Y, D and E. Although both D and E fragments seem to be able to bind with lysine binding sites of Glu-plasminogen, and to enhance the activation rate by UK, only binding of E fragment with plasminogen can result in enhancement of the activation of Glu-plasminogen by SK.
