FATTY ACID DESATURASES FROM PRIMULA

The invention relates generally to methods and compositions concerning desaturase enzymes that modulate the number and location of double bonds in long chain poly-unsaturated fatty acids (LC-PUFA's). In particular, the invention relates to methods and compositions for improving omega-3 fatty ac...

Zusammenfassung:	The invention relates generally to methods and compositions concerning desaturase enzymes that modulate the number and location of double bonds in long chain poly-unsaturated fatty acids (LC-PUFA's). In particular, the invention relates to methods and compositions for improving omega-3 fatty acid profiles in plant products and parts using desaturase enzymes and nucleic acids encoding for such enzymes. In particular embodiments, the desaturase enzymes are Primula .DELTA.6-desaturases. Also provided are improved soybean oil compositions having SDA and a beneficial overall content of omega-3 fatty acids relative to omega-6 fatty acids. L'invention se rapporte de manière générale à des procédés et à des compositions concernant des enzymes désaturases qui modulent le nombre et l'emplacement des doubles liaisons dans des acides gras poly-insaturés à chaîne longue (LC-PUFA). En particulier, l'invention se rapporte à des procédés et à des compositions permettant d'améliorer les profils d'acides gras oméga-3 dans des produits végétaux et des parties de plantes au moyen d'enzymes désaturases et d'acides nucléiques codant pour ces enzymes. Dans des modes de réalisation particuliers, les enzymes désaturases sont des .DELTA.6-désaturases de Primula. L'invention se rapporte également à des compositions d'huile de soja améliorées contenant du SDA et ayant une teneur globale bénéfique en acides gras oméga-3 relativement aux acides gras oméga-6.
