The OLE1 gene of Saccharomyces cerevisiae encodes the delta 9 fatty acid desaturase and can be functionally replaced by the rat stearoyl-CoA desaturase gene.


Strains of Saccharomyces cerevisiae bearing the ole1 mutation are defective in unsaturated fatty acid (UFA) synthesis and require UFAs for growth. A previously isolated yeast genomic fragment complementing the ole1 mutation has been sequenced and determined to encode the delta 9 fatty acid desaturase enzyme by comparison of primary amino acid sequence to… (More)
