Identification of a pair of phospholipid:diacylglycerol acyltransferases from developing flax (Linum usitatissiumum L.) seed catalyzing the selective production of trilinoleninDownload
The oil from flax (Linum usitatissimum L.) has high amounts of α-linolenic acid (ALA; 18:3cisΔ9,12,15) and is one of the richest sources of omega-3 polyunsaturated fatty acids (ω-3-PUFAs). To produce ∼57% ALA in triacylglycerol (TAG), it is likely that flax contains enzymes that can efficiently...
Neutral lipids are ubiquitously found in nature, serving primarily as energy storage compounds. The ability to control the rate of neutral lipid bioassembly is of particular interest in numerous applications. For example, restriction of triacylglycerol and steryl ester synthesis in mammals could...
High-performance variants of plant diacylglycerol acyltransferase 1 generated by directed evolution provide insights into structure functionDownload
Diacylglycerol acyltransferase 1 (DGAT1) catalyzes the acyl-CoA-dependent biosynthesis of triacylglycerol, the predominant component of seed oil. In some oil crops, including Brassica napus, the level of DGAT1 activity can have a substantial effect on triacylglycerol production....
Heterologous expression of flax PHOSPHOLIPID:DIACYLGLYCEROL CHOLINEPHOSPHOTRANSFERASE (PDCT) increases polyunsaturated fatty acid content in yeast and Arabidopsis seedsDownload
Background Flax (Linum usitatissimum L.) is an agriculturally important crop with seed oil enriched in α-linolenic acid (18:3 cisΔ9, 12, 15; ALA). This polyunsaturated fatty acid (PUFA) is the major determinant for the quality of flax seed oil in food, nutraceuticals and industrial applications....
Functional and topological analysis of yeast acyl-CoA:diacylglycerol acyltransferase 2, an endoplasmic reticulum enzyme essential for triacylglycerol biosynthesisDownload
Acyl-CoA:diacylglycerol acyltransferase (EC 22.214.171.124) is a membrane protein present mainly in the endoplasmic reticulum. It catalyzes the final and committed step in the biosynthesis of triacylglycerol, which is the principal repository of fatty acids for energy utilization and membrane...
