Substrate preferences of long-chain acyl-CoA synthetase and diacylglycerol acyltransferase contribute to enrichment of flax seed oil with a-linolenic acidDownload
Seed oil from flax (Linum usitatissimum) is enriched in a-linolenic acid (ALA; 18:3?9cis,12cis,15cis), but the biochemical processes underlying the enrichment of flax seed oil with this polyunsaturated fatty acid are not fully elucidated. Here, a potential process involving the catalytic actions...
Identification of genes associated with ricinoleic acid accumulation in Hiptage benghalensis via transcriptome analysisDownload
Background: Ricinoleic acid is a high-value hydroxy fatty acid with broad industrial applications.Hiptage benghalensis seed oil contains a high amount of ricinoleic acid (~80%) and represents an emerging source of this unusual fatty acid. However, the mechanism of ricinoleic acid accumulation in...
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...
Substrate preferences of long-chain acyl-CoA synthetase and diacylglycerol acyltransferase contribute to enrichment of flax seed oil with α -linolenic acidDownload
Seed oil from flax ( Linum usitatissimum ) is enriched in α -linolenic acid (ALA; 18:3 Δ 9 cis ,12 cis ,15 cis) but the biochemical processes underlying the enrichment of flax seed oil with this polyunsaturated fatty acid are not fully elucidated. Here, a potential process involving the catalytic...
Long-chain acyl-CoA synthetase (LACS, EC 18.104.22.168) 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...
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...
Background The cellulosic ethanol industry has developed efficient strategies for converting sugars obtained from various cellulosic feedstocks to bioethanol. However, any further major improvements in ethanol productivity will require development of novel and innovative fermentation strategies...
Multiple mechanisms contribute to increased neutral lipid accumulation in yeast producing recombinant variants of plant diacylglycerol acyltransferase 1Download
The apparent bottleneck in the accumulation of oil during seed development in some oleaginous plant species is the formation of triacylglycerol (TAG) by the acyl-CoA-dependent acylation of sn-1,2- diacylglycerol catalyzed by diacylglycerol acyltransferase (DGAT, EC 22.214.171.124). Improving DGAT...
Low temperature is one of the most common environmental stresses that seriously affect the growth and development of plants. However, plants have the plasticity in their defence mechanisms enabling them to tolerate and, sometimes, even survive adverse environmental conditions. MicroRNAs (miRNAs)...
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....
