1. An isolated fungal polypeptide having delta-15 desaturase activity comprising:
(a) an amino acid sequence that is at least 90% identical with SEQ ID NO:52, 54, 55, 58, 60, or 62, based on the Clustal W method of alignment, using the default parameters of GAP PENALTY=10, GAP LENGTH PENALTY=0.1, and Gonnet 250 series of protein weight matrix, wherein the amino acid sequence is not SEQ ID NO:50, 52, 54, 55, 58, 60, or 62; and (b) a delta-15 desaturase motif as set forth in SEQ ID NO:46. |
