A 10 kDa acyl-CoA binding protein (ACBP) from Brassica napus enhances acyl exchange between acyl-CoA and phosphatidylcholine
Download2009
Yurchenko, O. P., Stymne, S., Stahl, U., Moloney, M. M., Nykiforuk, C. L., Weselake, R. J. , Banas, A.
The gene encoding a 10-kDa acyl-CoA-binding protein (ACBP) from Brassica napus wasover-expressed in developing seeds of Arabidopsis thaliana. Biochemical analysis of T2andT3A. thaliana seeds revealed a significant increase in polyunsaturated fatty acids (FAs)(18:2cisD9,12and 18:3cisD9,12,15) at...

Castor oil contains approximately 90% ricinoleic acid (RA) which is stored mainly in the form of tri‐ricinoleic acid containing triacylglycerols (TAG). Ricinoleate is synthesized from oleate (18:1n‐9) esterified to the sn‐2 position of phosphatidylcholine (PtdCho) catalyzed by...

Characterization of Phosphatidylcholine Metabolism in Mouse Hepatocytes after Hepatectomy and in Primary Human Hepatocytes
DownloadSpring 2012
Phosphatidylcholine (PC) is the major component of mammalian membranes and the induction of PC biosynthesis has been shown to be an essential step in cell proliferation in various cell lines. In the liver, PC biosynthesis is regulated by two pathways: the CDP-choline and the...

Engineering Enhanced Performance in Plant Diacylglycerol Acyltransferase and Long-Chain Acyl-CoA Synthetase
DownloadSpring 2018
Triacylglycerol (TAG) is the major storage lipid in higher plants and has great nutritional and industrial value. Plant storage lipid biosynthesis involves different subcellular compartments and a complex network of enzymes and proteins. Among them, endoplasmic reticulum (ER)-bound diacylglycerol...

Choline is an essential micronutrient with increased requirements during pregnancy and lactation due to a high demand by the developing fetus and infant. Animal studies have demonstrated that choline is essential for brain development, and as a component of all cell membranes it is hypothesized...

Functional Characterization of Plant Patatin-like Phospholipase A III in Transgenic Arabidopsis thaliana Producing 18 Carbon Hydroxy Fatty Acids
DownloadFall 2016
Hydroxy fatty acid (HFA)-enriched oils are valuable in many oleo-chemical industries. The major natural source of HFA, however, is castor (Ricinus communis) seed, which is poisonous to human beings and animals. Although over-expressing a castor OLEATE 12-HYDROXYLASE (RcFAH12) in Arabiodpsis...

Identification of a pair of phospholipid:diacylglycerol acyltransferases from developing flax (Linum usitatissiumum L.) seed catalyzing the selective production of trilinolenin
Download2013
Wickramarathna, Aruna D., Siloto, Rodrigo M. P., Mietkiewska, Elzbieta, Pan, Xue, Weselake, Randall J.
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...

Impaired de novo choline synthesis explains why phosphatidylethanolamine N-methyltransferase-deficient mice are protected from diet-induced obesity
Download2010
Kuo, Ming-Shang, Dyck, Jason R. B., Sletten, Torunn, Proctor, Spencer D., Jacobs, René L., Lingrell, Susanne, Cao, Guoqing, Peake, David A., Kennedy, Brian P., Zhao, Yang, Vance, Dennis E., Koonen, Debby P. Y., Su, Brian
Phosphatidylcholine (PC) is synthesized from choline via the CDP-choline pathway. Liver cells can also synthesize PC via the sequential methylation of phosphatidylethanolamine, catalyzed by phosphatidylethanolamine N-methyltransferase (PEMT). The current study investigates whether or not hepatic...

Egg yolk contains approximately 10% (w/w) phospholipids (PL), of which about 70% is phosphatidylcholine (PC). Conventional methods of PL extraction from egg yolk involve using hazardous organic solvents. Supercritical carbon dioxide (SC-CO2), as a "green" solvent, had been applied for the...

In vivo and in vitro evidence for biochemical coupling of reactions catalyzed by lysophosphatidylcholine acyltransferase and diacyglycerol acyltransferase

Greer, Michael S., Pan, Xue, Weselake, Randall J., Chen, Guanqun, Zou, Jitao, Caldo, Kristian Mark P., Kazachkov, Michael
Seed oils of flax (Linum usitatissimum L.) and many other plant species contain substantial amounts of polyunsaturated fatty acids (PUFAs). Phosphatidylcholine (PC) is the major site for PUFA synthesis. The exact mechanisms of how these PUFAs are channeled from PC into triacylglycerol (TAG) needs...
