  • Patent number: 10767205
    Abstract: The present disclosure is directed to microorganisms that are genetically modified to express at least one exogenous enzyme involved in N-acetylglucosamine uptake and metabolism. Methods for the production of an exopolysaccharide are also disclosed. The exopolysaccharide comprises N-acetylglucosamine and D-glucose and may be used as a bioresorbable implant for soft tissue repair, replacement, or augmentation.
    Type: Grant

  • Patent number: 6958223
    Abstract: Incorporation of certain amino acid analogs into polypeptides produced by cells which do not ordinarily provide polypeptides containing such amino acid analogs is accomplished by subjecting the cells to growth media containing such amino acid analogs. The degree of incorporation can be regulated by adjusting the concentration of amino acid analogs in the media and/or by adjusting osmolality of the media. Such incorporation allows the chemical and physical characteristics of polypeptides to be altered and studied. In addition, nucleic acid and corresponding proteins including a domain from a physiologically active peptide and a domain from an extracellular matrix protein which is capable of providing a self-aggregate are provided. Human extracellular matrix proteins capable of providing a self-aggregate collagen are provided which are produced by prokaryotic cells. Preferred codon usage is employed to produce extracellular matrix proteins in prokaryotics.

  • Publication number: 20040018983
    Abstract: Methods for elucidating an antifungal or anti-yeast compound which selectively bind to a fungal or yeast zinc finger-containing protein within a fungus are disclosed. Assays of screening for compounds that are effective for binding to a fungal or yeast zinc finger-containing protein are also provided. It is also provided a pharmaceutical composition containing an effective amount of a compound or compounds identified as effective for binding to or associating with a fungal or yeast zinc finger-containing protein using the disclosed methods. Fungal and/or yeast infections can be treated or prevented by administering to a patient in need of treatment the pharmaceutical composition containing an effective amount of an compound or compounds identified as effective for binding to or associating with a fungal or yeast zinc finger-containing protein using the disclosed methods.
