摘要:
A method for synthesizing a protein of interest with a modified N-glycosylation profile within a plant, a portion of a plant, or a plant cell is provided. The method comprises co-expressing within a plant a nucleotide sequence encoding a first nucleotide sequence encoding a hybrid protein (GNT1-GalT) comprising a CTS domain of N-acetylglucosaminyl transferase (GNT1) fused to a catalytic domain of beta-1,4galactosyltransferase (GalT), the first nucleotide sequence operatively linked with a first regulatory region that is active in the plant, and a second nucleotide sequence for encoding the protein of interest, the second nucleotide sequence operatively linked with a second regulatory region that is active in the plant. The first and second nucleotide sequences are co-expressed to synthesize a protein of interest comprising glycans with the modified N-glycosylation profile within the plant, the portion of the plant, or the plant cell.
摘要:
The present invention concerns transformed Phaeodactylum tricomutum comprising a nucleic acid sequence operatively linked to a promoter, wherein said nucleic acid sequence encodes an N-acetylglucosaminyltransferase I and/or an a-Mannosidase II and wherein at least one β-Ν-acetylglucosaminidase of said transformed Phaeodactylum tricomutum has been inactivated; a method for producing a glycosylated polypeptide, said method comprising the steps of (i) culturing a transformed P. tricomutum as defined previously and (ii) purifying said polypeptide that is expressed and glycosylated in said transformed P. tricomutum; and the use of such a transformed P. tricomutum for producing a glycosylated polypeptide.
