Engineering increased triacylglycerol accumulation in Saccharomyces cerevisiae using a modified type 1 plant diacylglycerol acyltransferase
Abstract Diacylglycerol acyltransferase (DGAT) catalyzes the acyl-CoA-dependent acylation of sn-1,2-diacylglycerol to produce triacylglycerol (TAG). This enzyme, which is critical to numerous facets of oilseed development, has been highlighted as a genetic engineering target to increase storage lipi...

| 520 | |a Abstract Diacylglycerol acyltransferase (DGAT) catalyzes the acyl-CoA-dependent acylation of sn-1,2-diacylglycerol to produce triacylglycerol (TAG). This enzyme, which is critical to numerous facets of oilseed development, has been highlighted as a genetic engineering target to increase storage lipid production in microorganisms designed for biofuel applications. Here, four transcriptionally active DGAT1 genes were identified and characterized from the oil crop Brassica napus. Overexpression of each BnaDGAT1 in Saccharomyces cerevisiae increased TAG biosynthesis. Further studies showed that adding an N-terminal tag could mask the deleterious influence of the DGATs’ native N-terminal sequences, resulting in increased in vivo accumulation of the polypeptides and an increase of up to about 150-fold in in vitro enzyme activity. The levels of TAG and total lipid fatty acids in S. cerevisiae producing the N-terminally tagged BnaDGAT1.b at 72 h were 53 and 28 % higher than those in cultures producing untagged BnaA.DGAT1.b, respectively. These modified DGATs catalyzed the synthesis of up to 453 mg fatty acid/L by this time point. The results will be of benefit in the biochemical analysis of recombinant DGAT1 produced through heterologous expression in yeast and offer a new approach to increase storage lipid content in yeast for industrial applications. | ||

This enzyme, which is critical to numerous facets of oilseed development, has been highlighted as a genetic engineering target to increase storage lipid production in microorganisms designed for biofuel applications. Here, four transcriptionally active DGAT1 genes were identified and characterized from the oil crop Brassica napus. Overexpression of each BnaDGAT1 in Saccharomyces cerevisiae increased TAG biosynthesis. Further studies showed that adding an N-terminal tag could mask the deleterious influence of the DGATs’ native N-terminal sequences, resulting in increased in vivo accumulation of the polypeptides and an increase of up to about 150-fold in in vitro enzyme activity. The levels of TAG and total lipid fatty acids in S. cerevisiae producing the N-terminally tagged BnaDGAT1.b at 72 h were 53 and 28 % higher than those in cultures producing untagged BnaA.DGAT1.b, respectively. These modified DGATs catalyzed the synthesis of up to 453 mg fatty acid/L by this time point. The results will be of benefit in the biochemical analysis of recombinant DGAT1 produced through heterologous expression in yeast and offer a new approach to increase storage lipid content in yeast for industrial applications.

This enzyme, which is critical to numerous facets of oilseed development, has been highlighted as a genetic engineering target to increase storage lipid production in microorganisms designed for biofuel applications. Here, four transcriptionally active DGAT1 genes were identified and characterized from the oil crop Brassica napus. Overexpression of each BnaDGAT1 in Saccharomyces cerevisiae increased TAG biosynthesis. Further studies showed that adding an N-terminal tag could mask the deleterious influence of the DGATs’ native N-terminal sequences, resulting in increased in vivo accumulation of the polypeptides and an increase of up to about 150-fold in in vitro enzyme activity. The levels of TAG and total lipid fatty acids in S. cerevisiae producing the N-terminally tagged BnaDGAT1.b at 72 h were 53 and 28 % higher than those in cultures producing untagged BnaA.DGAT1.b, respectively. These modified DGATs catalyzed the synthesis of up to 453 mg fatty acid/L by this time point. The results will be of benefit in the biochemical analysis of recombinant DGAT1 produced through heterologous expression in yeast and offer a new approach to increase storage lipid content in yeast for industrial applications.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Yeast</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">DGAT</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Storage lipid synthesis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Biofuel</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Truksa, Martin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Deng, Wei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lung, Shiu-Cheung</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chen, Guanqun</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Weselake, Randall J.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Applied microbiology and biotechnology</subfield><subfield code="d">Berlin : Springer, 1975</subfield><subfield code="g">99(2014), 5 vom: 19.

Engineering increased triacylglycerol accumulation in Saccharomyces cerevisiae using a modified type 1 plant diacylglycerol acyltransferase |
| abstract |
Abstract Diacylglycerol acyltransferase (DGAT) catalyzes the acyl-CoA-dependent acylation of sn-1,2-diacylglycerol to produce triacylglycerol (TAG). This enzyme, which is critical to numerous facets of oilseed development, has been highlighted as a genetic engineering target to increase storage lipid production in microorganisms designed for biofuel applications. Here, four transcriptionally active DGAT1 genes were identified and characterized from the oil crop Brassica napus. Overexpression of each BnaDGAT1 in Saccharomyces cerevisiae increased TAG biosynthesis. Further studies showed that adding an N-terminal tag could mask the deleterious influence of the DGATs’ native N-terminal sequences, resulting in increased in vivo accumulation of the polypeptides and an increase of up to about 150-fold in in vitro enzyme activity. The levels of TAG and total lipid fatty acids in S. cerevisiae producing the N-terminally tagged BnaDGAT1.b at 72 h were 53 and 28 % higher than those in cultures producing untagged BnaA.DGAT1.b, respectively. These modified DGATs catalyzed the synthesis of up to 453 mg fatty acid/L by this time point. The results will be of benefit in the biochemical analysis of recombinant DGAT1 produced through heterologous expression in yeast and offer a new approach to increase storage lipid content in yeast for industrial applications. © Springer-Verlag Berlin Heidelberg 2014 |
