    摘要: The present invention relates to Δ17 desaturases, which have the ability to convert ω-6 fatty acids into their ω-3 counterparts (i.e., conversion of arachidonic acid [20:4, ARA] to eicosapentaenoic acid [20:5, EPA]). Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding Δ17 desaturases along with a method of making long-chain polyunsaturated fatty acids (PUFAs) using these Δ17 desaturases in oleaginous yeast are disclosed.

    摘要: The promoter region associated with the Yarrowia lipolytica ammonium transporter (yat1) gene has been found to be particularly effective for the expression of heterologous genes in oleaginous yeast. The promoter regions of the instant invention have been shown to be advantageously inducible under oleaginous conditions (i.e., nitrogen limitation) and are useful to drive expression of genes involved in the production of ω-3 and ω-6 fatty acids.
