Claims47
A method of producing an altered N-glycosylation form of a target protein, the method comprising:
- providing a Yarrowia lipolytica or an Arxula adeninivorans cell genetically engineered to express an α-1,2-mannosidase polypeptide;
- and
- introducing into the cell a nucleic acid encoding a target protein, wherein the cell produces the target protein in an altered N-glycosylation form.
An isolated Yarrowia lipolytica or Arxula adeninivorans cell genetically engineered to express an α-1,2-mannosidase polypeptide, wherein the cell is capable of producing a target protein in an altered glycosylation form if a nucleic acid encoding the target protein is introduced into the cell.
A method of producing an altered N-glycosylation form of a target protein, the method comprising contacting a target protein with a cell lysate prepared from a Yarrowia lipolytica or an Arxula adeninivorans cell genetically engineered to express an α-1,2-mannosidase polypeptide, wherein the contacting of the target protein with the cell lysate results in an altered N-glycosylation form of the target protein.
A substantially pure culture of Yarrowia lipolytica or Arxula adeninivorans cells, wherein the culture comprises a cell genetically engineered to express an α-1,2-mannosidase polypeptide, and wherein the cell is capable of producing a target protein in an altered glycosylation form if a nucleic acid encoding the target protein is introduced into the cell.
