Patent ID: 7777098

Claim:
A process for production of compounds comprising one or more C18-, C20-, and/or C22-polyunsaturated fatty acids in a transgenic organism comprising: a) introducing, into an organism, at least one nucleic acid sequence which encodes an ω-3-desaturase that is capable of desaturating C20- or C22-fatty acids, and b) culturing the organism under conditions which permits the production of one or more C18-, C20-, and/or C22-polyunsaturated fatty acids, wherein the ω-3-desaturase is encoded by a nucleic acid sequence comprising: i) the nucleic acid sequence of SEQ ID NO: 1, ii) a nucleic acid sequence encoding the amino acid sequence of SEQ ID NO: 2, iii) a nucleic acid sequence having at least 95% identity with the nucleic acid sequence of SEQ ID NO: 1, or iv) a nucleic acid sequence encoding an amino acid sequence having at least 95% identity with the amino acid sequence of SEQ ID NO: 2.
