Patent number: 8685679Abstract: Methods to increase the percent of polyunsaturated fatty acids (PUFAs) within the total lipids and oils of PUFA-producing oleaginous organisms are provided herein, by regulating the activity of specific acyltransferases. Specifically, since oil biosynthesis is expected to compete with polyunsaturation during oleaginy, it is possible to reduce or inactivate the activity of an organism's DAG ATs (e.g., phospholipid:diacylglycerol acyltransferase (PDAT) and/or diacylglycerol acyltransferase 1 (DGAT1) and/or diacylglycerol acyltransferase 2 (DGAT2)) to thereby reduce the overall rate of oil biosynthesis while concomitantly increasing the percent of PUFAs that are incorporated into the lipid and oil fractions. The teachings herein will thereby enable one to engineer a wide variety of oleaginous organisms to produce oils with very specific fatty acid compositions.Type: GrantFiled: July 27, 2005Date of Patent: April 1, 2014Assignee: E I du Pont de Nemours and CompanyInventors: Stephen K. Picataggio, Narendra S. Yadav, Hongxiang Zhang

Patent number: 8685681Abstract: 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, genes encoding diacylglycerol acyltransferase (DGAT1) have been isolated from Y. lipolytica and Mortierella alpina. 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.Type: GrantFiled: December 18, 2008Date of Patent: April 1, 2014Assignee: E I du Pont de Nemours and CompanyInventors: Narendra S.
