Identification of a Long-Chain Fatty Acid Elongase from Nannochloropsis sp. Involved in the Biosynthesis of Fatty Acids by Heterologous Expression in Saccharomyces cerevisiae

The marine microalga Nannochloropsis sp. contains various elongases and desaturases that are critical for biosynthesis of polyunsaturated fatty acids. A full-length cDNA encoding a long-chain fatty acid elongase, named NsFAE, was cloned from Nannochloropsis sp.. The open reading frame of NsFAE (GenBank accession no. MF680548) consisted of 1068bp and encoded a predicted protein of 355 amino acids with molecular mass 38.8kDa. The deduced...
