Fatty Acid Desaturase Gene

The methylotrophic yeast Pichia pastoris GS115, a widely used strain in production of various heterologous proteins, especially membrane-bound enzymes, can also produce linoleic and linolenic acids, which indicates the existence of membrane-bound Delta12 and Delta15-fatty acid desaturases. This paper describes the cloning and functional characterization of a novel Delta12-fatty acid desaturase gene from this methylotrophic yeast. The open reading frame of the gene (named Pp-FAD12) is 1263 bp in size and encodes a 420-amino-acid peptide. The deduced Pp-FAD12 protein shows high identity (50-67%) with Delta12-fatty acid desaturases from other fungi. It also shows a high identity (57%) with Delta15-fatty acid desaturase (named Sk-FAD15) from Saccharomyces kluyveri. Expression of Pp-FAD12 in polyunsaturated fatty acids non-producing yeast Saccharomyces cerevisiae demonstrated that its product converted oleic acid (18 : 1) to linoleic acid (18 : 2). This result suggests that Pp-FAD12 encodes a novel Delta12-fatty acid desaturase in P. pastoris GS115. This is the first report about the cloning and functional characterization of Delta12-fatty acid desaturase gene in methylotrophic yeast.
