  • Recombinant kinase from insect cells for the synthesis of nucleoside monophosphates
    Patent number: 7625735
    Abstract: A recombinant Drosophila melanogaster deoxynucleoside kinase that remains stable during the synthesis of nucleoside monophosphate without the addition of stabilizing SH reagents or stabilizing proteins, and that accepts all four natural deoxynucleotides is provided. In addition, the invention concerns DNA sequences, vectors, transformed cells, a method for production of the recombinant kinase as well as its use for preparing nucleoside monophosphates.
    Type: Grant
