Δ6-Desaturase from Mortierella alpina: cDNA cloning, expression, and phylogenetic analysis
The open reading frame of the Δ6-desaturase gene was isolated from Mortierella alpina W15 and the gene was cloned into a pPIC3.5K vector. The vector was transformed into Pichia pastoris GS115 and expression was i...

Identification of a fatty acid ∆6-desaturase gene from the eicosapentaenoic acid-producing fungus Pythium splendens RBB-5
A new full-length cDNA (PsD6) putatively encoding a ∆6-desaturase was cloned from the eicosapentaenoic acid-producing fungus Pythium splendens RBB-5. PsD6 contained an open reading frame of 1380 bp encoding a pro...
