  • Transgenic non-human mammals producing BSSL variants
    Patent number: 5763739
    Abstract: The present invention relates to novel polypeptides which are variants of Bile Salt-Stimulated Lipase (BSSL; EC 3.1.1.1). It also relates to DNA molecules encoding the said polypeptides, and to subproducts comprising the said DNA molecules. The invention further relates to processes for producing the said BSSL variants and for producing transgenic non-human mammals capable of expressing the BSSL variants.Furthermore the invention relates to such transgenic animals as well as to infant formulas comprising milk from such transgenic animals. The invention also relates to pharmaceutical compositions comprising the said polypeptides; and the use of the said polypeptides and DNA molecules for the manufacture of medicaments.

  • Plasmid for expressing phosphorylated recombinant proteins in a bacterial system
    Patent number: 5710044
    Abstract: The present invention provides a plasmid containing a promoter sequence, a nucleotide sequence encoding an exogenous protein, and a nucleotide sequence encoding an enzyme capable of modifying the exogenous protein. In a specific embodiment of the invention the encoded exogenous protein is human .beta.-casein and the encoded enzyme is a human kinase capable of phosphorylating recombinant .beta.-casein in a bacterial system. Phosphorylated recombinant human .beta.-casein having 3 or more phosphate groups and synthesized using the plasmid of the invention is shown to have the same bioactivity as native human .beta.-casein.

  • Tool for breaking, cutting or working of solid materials
    Patent number: 4921310
    Abstract: A tool for breaking, cutting, and working solid materials includes a rearwardly extending shaft adapted to be inserted into the bore of a holder. The shaft includes an annular groove located adjacent a rearmost end thereof. A cylindrical clip is mounted on the shaft for retaining the tool within the holder. The clip includes a longitudinal slot extending longitudinally completely therethrough. A rear free end of the clip is inwardly bent into the groove of the shaft to oppose longitudinal forward movement of the shaft relative to the clip.
