    Abstract: The present invention relates to polynucleotides from Cochliobolus heterostrophus C5, Cyanothece sp. CCY0110, Mycocentrospora acerin and Hyaloperonospora parasitica, which code for desaturases and which can be employed for the recombinant production of polyunsaturated fatty acids. The invention furthermore relates to vectors, host cells and transgenic nonhuman organisms which comprise the polynucleotides according to the invention, and to the polypeptides encoded by the polynucleotides. The invention furthermore relates to antibodies against the polypeptides according to the invention. Finally, the invention also relates to production processes for the polyunsaturated fatty acids and for oil, lipid and fatty acid compositions and to their use as drugs, cosmetics, foodstuffs, feedstuffs, preferably fish food, or food supplements.

    Abstract: The present invention relates to methods for the conversion of the substrate specificity of desaturases. Specifically, the present invention pertains to a method for the conversion of the substrate specificity of a Δ5 and/or Δ6 desaturase to the substrate specificity of a Δ4 desaturase, the method comprising: identifying regions and/or amino acid residues which control the substrate specificity of (i) the Δ5 and/or Δ6 desaturase and (ii) the Δ4 desaturase; and replacing in the amino acid sequence of the mentioned Δ5 and/or Δ6 desaturase, the regions and/or amino acid residues which control the substrate specificity of the Δ5 and/or Δ6 desaturase, by the corresponding regions and/or amino acid residues which control the substrate specificity of the Δ4 desaturase, thereby converting the substrate specificity of the Δ5 and/or Δ6 desaturase to the substrate specificity of the Δ4 desaturase. The present invention further concerns a method for the conversion of the substrate specificity of a Δ4 desaturase to the substrate specificity of a Δ5 and/or Δ6 desaturase, the method comprising: identifying regions and/or amino acid residues which control the substrate specificity of (i) the Δ4 desaturase and (ii) the Δ5 and/or Δ6 desaturase; and replacing in the amino acid sequence of the indicated Δ4 desaturase, the regions and/or amino acid residues which control the substrate specificity of the Δ4 desaturase, by the corresponding regions and/or amino acid residues which control the substrate specificity of the Δ5 and/or Δ6 desaturase, thereby converting the substrate specificity of the Δ4 desaturase to the substrate specificity of the Δ5 and/or Δ6 desaturase. In addition, the invention encompasses desaturases with converted substrate specificity.

    Abstract: The present invention relates to transgenic nucleic acids, expression cassettes, vectors, plant cells, plant organs and plants. The invention also relates to methods for increasing expression or activity of a target gene, particularly in a plant cell or plant organ, and also to uses of recombinant nucleic acids and expression cassettes to increase expression or activity of a target gene or for manufacturing of a vector, plant cell, plant organ or plant. Incidentally, the invention relates to enhancers for achieving increased expression or activity of a target gene, particularly in a plant cell or plant organ, when operably linked to a promoter functional in such plant cell, plant organ or plant. The invention is described herein with reference to the technical field of production of polyunsaturated fatty acids (PUFAs), without being limited to this technical field.For the production of desired molecules in plant cells, e.g. PUFAs, it is frequently required to express a target gene heterologous to the plant cell, or to overexpress a target gene naturally found in said plant cell.
