A Fluorescence‐Based Assay for Quantitative Analysis of Phospholipid:Diacylglycerol Acyltransferase ActivityDownload
Phospholipid:diacylglycerol acyltransferase (PDAT) catalyzes the acyl‐CoA‐independent triacylglycerol (TAG) biosynthesis in plants and oleaginous microorganisms and thus is a key target in lipid research. The conventional in vitro PDAT activity assay involves the use of radiolabeled substrates,...
GLYCEROL-3-PHOSPHATE ACYLTRANSFERASE (GPAT) genes encode enzymes involved in glycerolipid biosynthesis in plants. Ten GPAT homologues have been identified in Arabidopsis. GPATs 4–8 have been shown to be involved in the production of extracellular lipid barrier polyesters. Recently, GPAT9 was...
Punicic acid (PuA; 18: 3Δ 9cis,11trans,13cis ) is an unusual 18-carbon fatty acid bearing three conjugated double bonds. It has been shown to exhibit a myriad of beneficial bioactivities including anti-cancer, anti-diabetes, anti-obesity, antioxidant, and anti-inflammatory properties. Pomegranate...
The demand for vegetable oils is increasing at a rapid pace due to our ever-expanding population, growing global affluence, changing dietary choices, and the need for renewable plant-derived resources. However, oilseed production is negatively impacted by unpredictable environmental conditions...
Characterization of Type-2 Diacylglycerol Acyltransferases in the Green Microalga Chromochloris zofingiensisDownload
Diacylglycerol acyltransferase (DGAT) catalyzes the last and committed step of the acyl-CoA-dependent TAG biosynthesis and thus is a key target for manipulating oil production in microalgae. The microalga Chromochloris zofingiensis can accumulate substantial amounts of triacylglycerol (TAG) and...
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 a Type‐2 Diacylglycerol Acyltransferase from Haematococcus pluvialis Reveals Possible Allostery of the Recombinant EnzymeDownload
Haematococcus pluvialis is a green microalga used in the algal biotechnology industry that can accumulate considerable amounts of storage triacylglycerol (TAG) and astaxanthin, which is a high‐value carotenoid with strong antioxidant activity, under stress conditions. Diacylglycerol...
Characterization of the diversification of phospholipid:diacylglycerol acyltransferases in the green lineageDownload
Triacylglycerols have important physiological roles in photosynthetic organisms, and are widely used as food, feed and industrial materials in our daily life. Phospholipid:diacylglycerol acyltransferase (PDAT) is the pivotal enzyme catalyzing the acyl‐CoA‐independent biosynthesis of...
Downregulation of key genes involved in carbon metabolism in Medicago truncatula results in increased lipid accumulation in vegetative tissueDownload
Alfalfa (Medicago sativa L.) is the most widely grown perennial forage crop and is a close relative of the model diploid legume Medicago truncatula Gaertn. However, use of alfalfa leads to substantial greenhouse gas emissions and economic losses related to inefficiencies in rumen fermentation....
Long-chain acyl-CoA synthetase (LACS, EC 184.108.40.206) catalyzes the ATP-dependent activation of free fatty acid to form acyl-CoA, which in turn serves as the major acyl donor for various lipid metabolic pathways. Increasing the size of acyl-CoA pool by enhancing LACS activity appears to be a useful...
