  • N-glycosylation in transformed
    Patent number: 9587245
    Abstract: Transformed Phaeodactylum tricornutum including a nucleic acid sequence operatively linked to a promoter, wherein the nucleic acid sequence encodes an N-acetylglucosaminyltransferase I and/or an ?-Mannosidase II and wherein at least one ?-N-acetylglucosaminidase of the transformed Phaeodactylum tricornutum has been inactivated. A method for producing a glycosylated polypeptide includes the steps of (i) culturing a transformed P. tricornutum as defined previously and (ii) purifying the polypeptide that is expressed and glycosylated in the transformed P. Tricornutum. The use of such a transformed P. tricornutum for producing a glycosylated polypeptide is also described.
