Abstract
The present invention is directed to isolated nucleic acid molecules and polypeptides of thraustochytrid polyunsaturated fatty acid (PUFA) synthases involved in the production of PUFAs, including PUFAs enriched in docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), or a combination thereof. The present invention is directed to vectors and host cells comprising the nucleic acid molecules, polypeptides encoded by the nucleic acid molecules, compositions comprising the nucleic acid molecules or polypeptides, and methods of making and uses thereof.
