Abstract: The present invention discloses modified forms of plasmin with advantageous properties. As compared to their natural unmodified form, these variants exhibit significantly modulated kinetics in terms of delayed inhibition characteristics in the presence of specific inhibitors, such as ?2-antiplasmin (?2-AP). These include PEG-conjugated thiol derivatives of truncated plasmin with potential clinical applications in various regimens of thrombolytic therapies.

Abstract: Disclosed herein is an expression system for the production and secretion of biologically active clot-specific streptokinase (CSSK) protein in methylotrophic yeast. Yeast-expressed CSSK protein displays improved plasminogen activation and fibrin selectivity. Further disclosed are methylotrophic yeast transformed with at least one copy of functional cDNA sequence encoding CSSK adjunct with modified signal sequence which results in secretion of mature and correctly processed CSSK.

Abstract: The present invention relates to novel mutants of Streptokinase, its functional fragments and covalently modified forms. Methods are provided for the preparation of the bacterial plasminogen activator protein, Streptokinase its muteins, species variants and their covalently modified variants that are characterized by improved therapeutic properties, such as increased proteolytic stability, extended plasma half-lives, reduced immuno-reactivity and enhanced fibrin clot specificity. The method involves either incorporating additional cysteine residues, or substituting cysteine residues for naturally occurring amino acids into non-essential regions of the protein such that the catalytic activity of the resultant protein remains largely unaltered. These cysteine variants were further modified by covalently attaching a cysteine reactive polymer such as polyethylene glycol (PEG) or sulfhydryl-reactive moieties from a group that includes fluorophore, spin labels or other small conjugates.

Abstract: The present invention discloses novel hybrid proteins that have both plasminogen activator and anti-thrombotic properties, including clot specific action, that renders these as highly advantageous for the treatment of circulatory disorders involving fibrin clot formation due to underlying tissue damage in the blood vessels leading to myocardial infarction, strokes etc. Also disclosed are new proteins, and methods of obtaining the same, that help to dissolve blood clots by activating plasminogen in a plasmin or thrombin dependent manner and also inhibit both the activity and generation of thrombin through the intrinsic pathway of blood coagulation.

Abstract: The present invention provides polynucleotides encoding clot-specific streptokinase proteins possessing altered plasminogen characteristics, including enhanced fibrin selectivity. The kinetics of plasminogen activation by these proteins are distinct from those of natural streptokinase, in that there is a temporary delay or lag in the initial rate of catalytic conversion of plasminogen to plasmin. Also disclosed are processes for preparing the proteins.
