Patent ID: 8088906

Claim:
An isolated nucleic acid molecule selected from the group consisting of: a) an isolated nucleic acid molecule comprising the nucleotide sequence set forth in SEQ ID NO: 5; b) an isolated nucleic acid molecule which encodes a polypeptide comprising the amino acid sequence set forth in SEQ ID NO: 6; c) an isolated nucleic acid molecule comprising a nucleotide sequence which is at least 95% identical to the nucleotide sequence set forth in SEQ ID NO: 5 and wherein the nucleic acid molecule encodes a Δ5 fatty acid desaturase molecule capable of converting 20:3(n-6) fatty acid to arachidonic acid; d) an isolated nucleic acid molecule comprising a nucleotide sequence which is at least 95% identical to the nucleotide sequence set forth in SEQ ID NO: 5 and wherein the nucleic acid molecule encodes a Δ5 fatty acid desaturase molecule capable of converting 20:4(n-3) fatty acid to eicosapentaenoic acid; e) an isolated nucleic acid molecule which encodes a polypeptide comprising an amino acid sequence which is at least 95% identical to the amino acid sequence set forth in SEQ ID NO: 6 and wherein the polypeptide is a Δ5 fatty acid desaturase molecule capable of converting 20:3(n-6) fatty acid to arachidonic acid; and f) an isolated nucleic acid molecule which encodes a polypeptide comprising an amino acid sequence which is at least 95% identical to the amino acid sequence set forth in SEQ ID NO: 6 and wherein the polypeptide is a Δ5 fatty acid desaturase molecule capable of converting 20:4(n-3) fatty acid to eicosapentaenoic acid.
