Abstract: Fusion proteins having thermostable blunt-end ligase activity are provided. Blunt-end ligases are useful for DNA amplification, sequencing, production of recombinant DNA and recombinant fusion proteins, and other purposes. These thermostable blunt-end DNA ligases are useful in ligation schemes which include, e.g., an incubation at about 60-65° C. or higher, or as high as about 94° C., or at other temperatures. The ligases disclosed herein may enable high temperature blunt-end ligation without need for molecular crowding agents, and so may be useful for many nucleic acid ligation-amplification schemes, e.g., ones which operate at a uniform temperature (e.g., at about 60° C. or higher), including ones which require temperature cycling, e.g., from about 94° C. to about 60° C. (or higher) for one, two, three, or more cycles.

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.
