Characterization of Type-2 Diacylglycerol Acyltransferases in the Green Microalga Chromochloris zofingiensis
Download2018-12-13
Xu, Yang, Falarz, Lucas, Chen, Guanqun
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...

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....

Shah, Saleh, Xu, Yang, Ramakrishnan, Geetha, Caldo, Kristian Mark P., Chen, Guanqun, Ozga, Jocelyn, Greer, Michael S., Lemieux, M. Joanne, Wu, Limin, Weselake, Randall J.
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 2.3.1.20). Improving DGAT...

Properties and Biotechnological Applications of Acyl‐CoA:diacylglycerol Acyltransferase and Phospholipid:diacylglycerol Acyltransferase from Terrestrial Plants and Microalgae

Xu, Yang, Caldo, Kristian Mark P., Pal‐Nath, Dipasmita, Ozga, Jocelyn, Lemieux, M. Joanne, Weselake, Randall J., Chen, Guanqun
Triacylglycerol (TAG) is the major storage lipid in most terrestrial plants and microalgae, and has great nutritional and industrial value. Since the demand for vegetable oil is consistently increasing, numerous studies have been focused on improving the TAG content and modifying the fatty‐acid...

Substrate preferences of long-chain acyl-CoA synthetase and diacylglycerol acyltransferase contribute to enrichment of flax seed oil with a-linolenic acid
Download2018-04-01
Xu, Yang, Holic, Roman, Li, Darren, Pan, Xue, Mietkiewska, Elzbieta, Chen, Guanqun, Ozga, Jocelyn, Weselake, Randall J.
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...
