Phospholipid:diacylglycerol acyltransferase: an enzyme that catalyzes the acyl-CoA-independent formation of triacylglycerol in yeast and plants.
Triacylglycerol (TAG) is known to be synthesized in a reaction that uses acyl-CoA as acyl donor and diacylglycerol (DAG) as acceptor, and which is catalyzed by the enzyme acyl-CoA:diacylglycerolExpand
Storage Lipid Synthesis Is Non-essential in Yeast*
Steryl esters and triacylglycerol (TAG) are the main storage lipids in eukaryotic cells. In the yeastSaccharomyces cerevisiae, these storage lipids accumulate during stationary growth phase withinExpand
Biochemical pathways in seed oil synthesis.
Oil produced in plant seeds is utilized as a major source of calories for human nutrition, as feedstocks for non-food uses such as soaps and polymers, and can serve as a high-energy biofuel. TheExpand
High-value oils from plants.
The seed oils of domesticated oilseed crops are major agricultural commodities that are used primarily for nutritional applications, but in recent years there has been increasing use of these oilsExpand
Cloning and Functional Characterization of a Phospholipid:Diacylglycerol Acyltransferase from Arabidopsis1
A new pathway for triacylglycerol biosynthesis involving a phospholipid:diacylglycerol acyltransferase (PDAT) was recently described (Dahlqvist A, Stahl U, Lenman M, Banas A, Lee M, Sandager L, RonneExpand
Ricinoleic acid biosynthesis and triacylglycerol assembly in microsomal preparations from developing castor-bean (Ricinus communis) endosperm.
Microsomal membrane preparations from the developing endosperm of castor bean (Ricinus communis) catalysed the transfer of oleate from [14C]oleoyl-CoA to phosphatidylcholine (PtdCho). In the presenceExpand
Fatty Acid Phytyl Ester Synthesis in Chloroplasts of Arabidopsis[W]
This work identifies two phytyl ester synthases that act in fatty acid phytyl ester synthesis in chloroplasts during senescence and nitrogen deprivation to maintain the integrity of theExpand
Identification of non-heme diiron proteins that catalyze triple bond and epoxy group formation.
Acetylenic bonds are present in more than 600 naturally occurring compounds. Plant enzymes that catalyze the formation of the Delta12 acetylenic bond in 9-octadecen-12-ynoic acid and the Delta12Expand
Evidence for the reversibility of the acyl-CoA:lysophosphatidylcholine acyltransferase in microsomal preparations from developing safflower (Carthamus tinctorius L.) cotyledons and rat liver.
Acyl exchange between acyl-CoA and position 2 of sn-phosphatidylcholine occurs in the microsomal preparations of developing safflower cotyledons. Evidence is presented to show that the acyl exchangeExpand
8 – Triacylglycerol Biosynthesis
Publisher Summary This chapter discusses triacylglycerol biosynthesis. The outstanding problems in oil biosynthesis are numerous and offer many exciting challenges that are still of a sufficientlyExpand
