Metabolomics involves the high throughput characterization of small molecules or metabolites in cells, tissues and organisms. To interpret, store and exchange metabolomic data it is necessary to have comprehensive, electronically accessible databases that can be used to handle both 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...

Evolutionary and biochemical characterization of a Chromochloris zofingiensis MBOAT with wax synthase and DGAT activity
Download2021-01-01
Xu, Yang, Pan, Xue, Lu, Junhao, Wang, Juli, Shan, Qiyuan, Stout, Jake, Chen, Guanqun
Abstract: Wax synthase (WS) catalyzes the last step in wax ester biosynthesis in green plants. Two unrelated subfamilies of WS including the bifunctional acyltransferase and plant-like WS have been reported, but the latter is largely uncharacterized in microalgae. Here, we functionally...

Functional and topological analysis of yeast acyl-CoA:diacylglycerol acyltransferase 2, an endoplasmic reticulum enzyme essential for triacylglycerol biosynthesis
Download2011
Siloto, Rodrigo M. P., Snyder, Crystal L., Liu, Qin, Weselake, Randall J.
Acyl-CoA:diacylglycerol acyltransferase (EC 2.3.1.20) 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...

Functional interaction between phosducin-like protein 2 and cytosolic chaperonin is essential for cytoskeletal protein function and cell cycle progression
Download2007
Pozniakovsky, A., Hyman, A.A., Stirling, P.C., Takhar, K.S., Srayko, M., Lerou, M.R.
The Chaperonin Containing Tcp1 (CCT) maintains cellular protein folding homeostasis in the eukaryotic cytosol by assisting the biogenesis of many proteins, including actins, tubulins, and regulators of the cell cycle. Here, we demonstrate that the essential and conserved eukaryotic phosducin-like...

Heterologous expression of flax PHOSPHOLIPID:DIACYLGLYCEROL CHOLINEPHOSPHOTRANSFERASE (PDCT) increases polyunsaturated fatty acid content in yeast and Arabidopsis seeds
Download2015
Weselake, Randall J., Mietkiewska, Elzbieta, Pan, Xue, Singer, Stacy D., Siloto, Rodrigo M. P., Wickramarathna, Aruna D.
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....

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...

In vivo and in vitro evidence for biochemical coupling of reactions catalyzed by lysophosphatidylcholine acyltransferase and diacyglycerol acyltransferase
Download2015
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...

Inactivation of Saccharomyces cerevisiae and Candida humilis in Potassium Phosphate Buffer by Pulsed Electric Fields
DownloadSpring 2016
Pulsed electric field (PEF) is a promising athermal food preservation technology, having the potential to provide a better balance between food safety and food quality. But the high cost of PEF treatment has limited the commercial application of this technology. The aim of this MSc thesis...

Kinetic improvement of an algal diacylglycerol acyltransferase 1 via fusion with an acyl-CoA binding protein

Xu, Yang, Caldo, Kristian Mark P., Falarz, Lucas, Jayawardhane, Kethmi, Chen, Guanqun
SUMMARY Microalgal oils in the form of triacylglycerols (TAGs) are broadly used as nutritional supplements and biofuels. Diacylglycerol acyltransferase (DGAT) catalyzes the final step of acyl-CoA-dependent biosynthesis of TAG and is considered a key target for manipulating oil production....
