  • Elongase gene and uses thereof
    Patent number: 6403349
    Abstract: The subject invention relates to the identification of a gene involved in the elongation of polyunsaturated fatty acids (i.e., “elongase”) and to uses thereof. In particular, elongase is utilized in the conversion of gamma linolenic acid (GLA) to dihomogamma linolenic acid (DGLA) and in the conversion of 20:4n-3 to eicosapentaenoic acid (EPA). DGLA may be utilized in the production of polyunsaturated fatty acids, such as arachidonic acid (AA) which may be added to pharmaceutical compositions, nutritional compositions, animal feeds, as well as other products such as cosmetics.
