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 transporter protein 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.
Claims9
A yeast cell genetically modified to produce one or more human milk oligosaccharides, wherein the yeast cell comprises (i) a heterologous nucleic acid encoding a human milk oligosaccharide (HMO) ABC transporter polypeptide;
- and (ii) one or more heterologous nucleic acids that each independently encode at least one enzyme of a human milk oligosaccharide biosynthetic pathway.
