Abstract:
1. An isolated microbial host cell comprising an isolated polynucleotide comprising: (a) a nucleotide sequence encoding a polypeptide having Δ8 desaturase activity, wherein the polypeptide has at least 90% amino acid identity, based on the Clustal V method of alignment, when compared to an amino acid sequence selected from the group consisting of: SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23 and SEQ ID NO:24; (b) a nucleotide sequence encoding a polypeptide having Δ8 desaturase activity, wherein the nucleotide sequence has at least 90% sequence identity, based on the BLASTN method of alignment, when compared to a nucleotide sequence selected from the group consisting of: SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20 and SEQ ID NO:39; or (c) a complement of the nucleotide sequence of (a) or (b), wherein the complement and the nucleotide sequence consist of the same number of nucleotides and are 100% complementary.
