  • Publication number: 20210189002
    Abstract: The invention provides a recombinant Thraustochytriaceae cell for the production of a glycomolecule. The cell comprises a nucleic acid encoding a heterologous glycomolecule, and a sequence encoding a heterologous oligosaccharyltransferase. The cell produces the heterologous glycomolecule having a higher glycan occupancy compared to the same heterologous glycomolecule produced by a corresponding cell not comprising the heterologous oligosaccharyltransferase. The glycan occupancy can be more than 25%. The cells advantageously produce and, optionally secrete, the heterologous glycomolecule. Thus, the invention provides recombinant organisms that provide glycomolecules having a glycosylation profile that is more similar to the glycosylation profile produced in a manunalian cell.

  • Publication number: 20210087540
    Abstract: The invention provides a recombinant Labyrinthulomycetes cell for the production of a low sulfate glycomolecule. The cell comprises a nucleic acid encoding a heterologous glycomolecule, and a sequence encoding a heterologous oligosaccharyltransferase. The cell produces the heterologous glycomolecule having fewer sulfated glycans compared to the same heterologous glycomolecule produced by a corresponding cell not comprising the heterologous oligosaccharyltransferase. The cells advantageously produce and, optionally secrete, the heterologous glycomolecule. Thus, the invention provides recombinant organisms that provide glycomolecules having a glycosylation profile that is more similar to the glycosylation profile produced in mammalian cell.

  • Patent number: 10087161
    Abstract: The present invention provides methods of method of synthesizing 2,5-furan dicarboxylic acid (FDCA) and FDCA precursor molecules. The methods involve performing a chemical dehydration reaction on a gluconic acid derivative in the presence of a dehydration catalyst. In some embodiments the gluconic acid derivative can be 2-dehydro-3-deoxy gluconic acid (DHG) or an ester thereof, 2-ketogluconic acid (2KGA) or an ester thereof, and 5-ketogluconic acid (5KGA) or an ester thereof. The 2,5-furan dicarboxylic acid precursor molecule is thereby synthesized, which can be converted into FDCA. The chemical dehydration can be performed by a variety of acid basic catalysts.

  • Patent number: 9909154
    Abstract: The present invention provides methods of producing dicarboxylic acids. The methods involve incubating a fatty acid or hydrocarbon substrate with an enzyme to produce a dicarboxylic acid product. The enzyme acts on the substrate to produce a product that has been both over-oxidized and has undergone cleavage of a C—C bond. In some embodiments the enzymes having these useful characteristics are mutants of a cytochrome P450 enzyme, for example an enzyme of the class CYP102 or a mutant thereof. The invention provides enzymes where these desirable characteristics can be found in a single enzyme, and thus in some embodiments the methods can be performed through the action of a single enzyme.

  • Publication number: 20170088865
    Abstract: The present invention provides methods for producing a product of one or more enzymatic pathways. The pathways used in the methods of the invention involve one or more conversion steps such as, for example, an enzymatic conversion of guluronic acid into D-glucarate (Step 7); an enzymatic conversion of 5-ketogluconate (5-KGA) into L-Iduronic acid (Step 15); an enzymatic conversion of L-Iduronic acid into Idaric acid Step 7b); and an enzymatic conversion of 5-ketocluconate into 4,6-dihydroxy 2,5-diketo hexanoate (2,5-DDH) (Step 16). In some embodiments the methods of the invention produce 2,5-furandicarboxylic acid (FDCA) as a product. The methods include both enzymatic and chemical conversions as steps. Various pathways are also provided for converting glucose into 5-dehdyro-4-deoxy-glucarate (DDG), and for converting glucose into 2,5-furandicarboxylic acid (FDCA).
