  • Acyltrasferases for alteration of polyunsaturated fatty acids and oil content in oleaginous yeasts
    Publication number: 20080124786
    Abstract: Two acyltransferases are provided, suitable for use in the manufacture of microbial oils enriched in omega fatty acids in oleaginous yeast (e.g., Yarrowia lipolytica). Specifically, the genes encoding phophatidylcholine-diacylglycerol acyltransferase (PDAT) and diacylglycerol acyltransferase (DGAT2) have been isolated from Y. lipolytica. These genes encode enzymes that participate in the terminal step in oil biosynthesis in yeast. Each is expected to play a key role in altering the quantity of polyunsaturated fatty acids produced in oils of oleaginous yeasts.
