Abstract
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 plants and oleaginous yeast is disclosed.
Claims3
An isolated nucleic acid molecule selected from the group consisting of:
- a.) an isolated nucleotide sequence encoding a Δ17 desaturase enzyme as set forth in SEQ ID NO:7;
- or,
- b.) an isolated nucleotide sequence that is completely complementary to (a).
Dependencies are inferred from the claim text.
