Novel Fatty Acid Desaturases And Elongases And Uses Thereof (Patent CA 2768082 A1)

The invention provides isolated nucleic acid molecules which encode novel fatty acid desaturases and elongases from the organism Emiliana huxleyi. The invention also provides recombinant expression vectors containing desaturase or elongase nucleic acid molecules, host cells into which the expression vectors have been introduced, and methods for large-scale production of long chain polyunsaturated fatty acids (LCPUFAs), e.g. arachidonic acid (ARA), eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA).
