  • Patent number: 9127282
    Abstract: The present invention discloses systems and methods for altering the color of bacterial bioluminescence via a fusion protein complex by fusing Discosoma sp. fluorescent protein mOrange (mOrange) with Vibrio harveyi luciferase. The fusion of mOrange to the N- or C-terminus of either ? or ? subunit of luciferase, via a short peptide linker produces fully active fusion enzymes. The fusion of mOrange to the N-terminus of luciferase ? gives rise to a new 560-nm emission component. The same methodology may be used to alter bacterial bioluminescence color by covalent attachment of other suitable fluorescent proteins or chromophores to luciferase for generating multi-color sensors.

  • Patent number: 9115210
    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.
