  • Vectors and process for producing high purity 6,12-dideoxyerythromycin A by fermentation
    Patent number: 5801032
    Abstract: A process for producing high purity 6,12-dideoxyerythromycin A using recombinant DNA technology is disclosed. The erythromycin producing strain, Saccharopolyspora erythraea, lacking the erythromycin C-12 and C-6 hydroxylases produces a mixture of 6,12-dideoxyerythromycin A and the precursor molecule, 6-deoxyerythromycin D. To achieve conversion of the precursor to the final product, a second copy of eryG is inserted into a non-essential region of the Sac. erythraea chromosome resulting in high purity 6,12-dideoxyerythromycin A.
    Type: Grant
    Filed: August 1, 1996
    Date of Patent: September 1, 1998
    Assignee: Abbott Laboratories
    Inventors: Diane L. Stassi, Gregory T. Maine, David A. Post, Mark T. Satter
