摘要：

The present invention relates to a &Dgr；5 desaturase, which has the ability to convert dihomo-&gamma；-linolenic acid (DGLA； 20:3 &omega；-6) to arachidonic acid (ARA； 20:4 &omega；-6) and/or eicosatetraenoic acid (ETA； 20:4 &omega；-3) to eicosapentaenoic acid (EPA； 20:5 &omega；-3). Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding &Dgr；5 desaturase along with a method of making long chain polyunsaturated fatty acids (PUFAs) using this &Dgr；5 desaturase in oleaginous yeast are disclosed.
