Patent

CA 2442010

The invention relates to a new elongase gene having the sequence SEQ ID NO: 1 or its derivatives, to a gene construct comprising this sequence or its derivatives and to its use. The inventive nucleic acid sequence encodes a polypeptide which elongates .alpha.-linolenic acid (C18:3 d9, 12, 15) by at least two carbon atoms whereas .gamma.-linolenic acid (C 18:3 d6, 9, 12) is not elongated. The invention additionally relates to vectors or organisms comprising an elongase gene having the sequence SEQ ID NO: 1 or its derivatives. The invention further relates to a process for the production of polyunsaturated fatty acids (=PUFAs) with an organism which comprises the elongase gene and which organism produces high amounts of oils and especially oils with a high content of unsaturated fatty acids. Additionally the invention relates to an oil and/or fatty acid composition with a higher content of polyunsaturated C20 or C22 fatty acids with at least two double bonds and/or to a triacylglycerol composition with a higher content of said polyunsaturated fatty acids.

L'invention concerne un nouveau gène d'élongase représenté par la séquence SEQ ID NO: 1, ou ses dérivés, un gène chimère contenant cette séquence, ou ses dérivés, ainsi que son utilisation. Cette séquence d'acides nucléiques code un polypeptide qui allonge l'acide .alpha.-linoléique (C¿18:3? ¿d9?, ¿12?, ¿15?) d'au moins deux atomes de carbone, l'acide .gamma.-linoléique (C¿18:3? ¿d9?, ¿9?, ¿12?) n'étant pas allongé. Par ailleurs, l'invention concerne des vecteurs ou des organismes comprenant un gène d'élongase représenté par la séquence SEQ ID NO: 1, ou ses dérivés. L'invention concerne également un procédé de production d'acides gras polyinsaturés (=PUFA) à partir d'un organisme comprenant ce gènes d'élongase. Cet organisme produit des quantités élevées d'huiles, particulièrement des huiles riches en acides gras insaturés. De plus, l'invention concerne une composition à base d'huile et/ou d'acides gras qui présente une plus forte teneur en acides gras C¿20? ou C¿22? polyinsaturés, avec au moins deux liaisons doubles, et/ou une composition triacylglycérol à plus forte teneur en acides gras polyinsaturés.
