  • Patent number: 12522849
    Abstract: The compositions and methods of the disclosure can be used to produce a cannabinoid in a host cell, such as a yeast cell. For example, the disclosure features host cells (e.g., yeast cells) modified to express one or more enzymes of a cannabinoid biosynthetic pathway, such as an acyl activating enzyme (AAE), a tetraketide synthase (TKS), a cannabigerolic acid synthase (CBGaS), and/or an olivetolic acid cyclase (OAC).

  • Publication number: 20250340826
    Abstract: Provided herein are genetically modified yeast cells capable of producing one or more human milk oligosaccharides (HMOs) and methods of making such cells. The yeast cells are engineered to comprise a heterologous nucleic acid encoding a variant ABC transporter protein YOR1 from Saccharomyces cerevisiae with improved 2?-fucosyllactose export activity and one or more heterologous nucleic acids that encode enzymes of a HMO biosynthetic pathway. Also provided are fermentation compositions including the disclosed genetically modified yeast cells, and related methods of producing and recovering HMOs generated by the yeast cells.

  • Publication number: 20250002953
    Abstract: The present disclosure features compositions and methods for producing one or more cannabinoids, such as cannabidiolic acid (CBDa) or cannabidiol (CBD), in a host cell, such as a yeast cell, that is genetically modified to express the enzymes of a cannabinoid biosynthetic pathway. Using the compositions and methods of the present invention, the host cell may be genetically modified to express one or more enzymes of a cannabinoid biosynthetic pathway, such as CBDaS. The host cell may be cultured in the medium in the presence of a first cannabinoid, for example CBGa, and incubated for a time sufficient to allow for bioconversion of the first cannabinoid to a second cannabinoid, for example CBDa, by the host cell.

  • Publication number: 20240327881
    Abstract: The present disclosure features compositions and methods for producing one or more isoprenoid compounds, such as gamma-ambryl acetate (GAA), in a host cell, such as a yeast cell, that is genetically modified to express the enzymes of an isoprenoid biosynthetic pathway, such as a pathway for making GAA. Using the compositions and methods of the present invention, the host cell may be genetically modified to express one or more enzymes of an isoprenoid biosynthetic pathway, such as an enzyme capable of converting manooloxy to GAA. The host cell may be cultured in a medium, for example, in the presence of an agent that regulates expression of the one or more enzymes. The host cell may be incubated for a time sufficient to allow for production of an isoprenoid compound, such as GAA. The isoprenoid compound may then be separated from the host cell or from the medium.

  • Publication number: 20240327875
    Abstract: The present disclosure features compositions and methods for producing one or more isoprenoid compounds, such as E-copalol, in a host cell, such as a yeast cell, that is genetically modified to express the enzymes of an isoprenoid biosynthetic pathway, such as a pathway for making E-copalol. Using the compositions and methods of the present invention, the host cell may be genetically modified to express one or more enzymes of an isoprenoid biosynthetic pathway, such as a copalyl-diphosphate (CPP) pyrophosphatase. The host cell may then be cultured in a medium, for example, in the presence of an agent that regulates expression of the one or more enzymes. The host cell may further be incubated for a time sufficient to allow for production of an isoprenoid compound, such as E-copalol, by the host cell. The isoprenoid compound may then be separated from the host cell or from the medium.
