  • Publication number: 20220380737
    Abstract: DGA1 catalyzes the final enzymatic step for converting acyl-CoA and 1,2-diacylglycerol to triacylglycerols (TAG) and CoA in yeast. Disclosed are methods for expression in an oleaginous yeast host of polynucleotide sequences encoding DGA1 from Rhodosporidium toruloides, Lipomyces starkeyi, Aurantiochytrium limacinum, Aspergillus terreus, or Claviceps purpurea. Also described herein are engineered recombinant host cells of Yarrowia lipolytica comprising heterologous DGA1 polynucleotides encoding DGA1 proteins, or functionally active portions thereof, having the capability of producing increased lipid production and possessing the characteristic of enhanced glucose consumption efficiency.

  • Patent number: 11492647
    Abstract: Disclosed are methods and compositions for increasing the triacylglycerol content of a cell by increasing the activity of a type 1 diacylglycerol acyltransferase (i.e., DGA2) and increasing the activity of a type 2 diacylglycerol acyltransferase (i.e., DGA1). In some embodiments, the triacylglycerol content of a cell is also modified my decreasing the activity of a triacylglycerol lipase in the same cell. Also disclosed are methods and compositions for increasing the triacylglycerol content of a cell by increasing the activity of a type 1 diacylglycerol acyltransferase (i.e., DGA2), or by increasing the activity of a type 3 diacylglycerol acyltransferase (i.e., DGA3).

  • Patent number: 10724041
    Abstract: Disclosed are nucleotide sequences and corresponding amino acid sequences of Arxula adeninivorans genes that can be utilized to manipulate the lipid content and/or composition of a cell. Methods and compositions for utilizing this information are disclosed to increase the lipid content or modify the lipid composition of a cell by either increasing or decreasing the activity of certain genetic targets.

  • Publication number: 20200109377
    Abstract: Disclosed are methods and compositions for increasing the triacylglycerol content of a cell by up-regulating diacylglycerol acyltransferase and down-regulating triacylglycerol lipase. In some embodiments, a DGA1 protein is expressed and a native TGL3 gene is knocked out, thereby increasing the synthesis of triacylglycerol and decreasing its consumption, respectively.

  • Patent number: 10428322
    Abstract: The present invention provides for heterologous expression of termite and termite-associated symbiont cellulases. The cellulases can, for example, be codon-optimized and expressed in yeast host cells, such as the yeast Saccharomyces cerevisiae. The cellulases can also be co-expressed in host cells with other cellulases. The expression in such host cells of the termite and termite-associated symbiont cellulases, and variants and combinations thereof, result in yeast with improved cellulosic activity. Thus, such genes and expression systems are useful for efficient and cost-effective consolidated bioprocessing systems.
