Abstract
The present invention relates to a Δ9 desaturase, which has the ability to convert palmitic acid [16:0] or stearic acid [18:0] into palmitoleic acid [16:1] or oleic acid [18:1], respectively. Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding Δ9 desaturase along with a method of making long chain polyunsaturated fatty acids (PUFAs) using this Δ9 desaturase in oleaginous yeast is disclosed.
