1 tPA Point Mutation at Autolysis Loop Enhances Resistance to PAI-1 Inhibition and Catalytic Activity. Tetradecanoylphorbol Acetate serpin family E member 1 Homo sapiens
2 To improve the proteolytic properties of tPA to enhance thrombolytic therapy, we designed a series of mutants in tPA serine protease domain (tPA-SPD) based on the crystal structure of tPA-SPD:plasminogen activators inhibitor-1 (PAI-1) complex that we determined recently. Tetradecanoylphorbol Acetate serpin family E member 1 Homo sapiens
3 To improve the proteolytic properties of tPA to enhance thrombolytic therapy, we designed a series of mutants in tPA serine protease domain (tPA-SPD) based on the crystal structure of tPA-SPD:plasminogen activators inhibitor-1 (PAI-1) complex that we determined recently. Tetradecanoylphorbol Acetate serpin family E member 1 Homo sapiens
4 To improve the proteolytic properties of tPA to enhance thrombolytic therapy, we designed a series of mutants in tPA serine protease domain (tPA-SPD) based on the crystal structure of tPA-SPD:plasminogen activators inhibitor-1 (PAI-1) complex that we determined recently. Tetradecanoylphorbol Acetate serpin family E member 1 Homo sapiens
5 To improve the proteolytic properties of tPA to enhance thrombolytic therapy, we designed a series of mutants in tPA serine protease domain (tPA-SPD) based on the crystal structure of tPA-SPD:plasminogen activators inhibitor-1 (PAI-1) complex that we determined recently. Tetradecanoylphorbol Acetate serpin family E member 1 Homo sapiens
6 We found that the A146Y substitution in tPA-SPD(A146Y) enhanced resistance to PAI-1 inactivation by 30-fold compared with original tPA-SPD. Tetradecanoylphorbol Acetate serpin family E member 1 Homo sapiens
7 We found that the A146Y substitution in tPA-SPD(A146Y) enhanced resistance to PAI-1 inactivation by 30-fold compared with original tPA-SPD. Tetradecanoylphorbol Acetate serpin family E member 1 Homo sapiens
8 Together, our findings reveal novel functions of A146Y variant, which not only increases the catalytic efficiency of the enzyme, but also enhances resistance to PAI-1 inhibition, and demonstrating that tPA-SPD (A146Y) variant is a much improved agent for thrombolytic therapy. Tetradecanoylphorbol Acetate serpin family E member 1 Homo sapiens
