    摘要: The present invention relates to a process for the modification of a glycoprotein, using a β-(1,4)-N-acetylgalactosaminyltransferase or a mutant thereof. The process comprises the step of contacting a glycoprotein comprising a glycan comprising a terminal GlcNAc-moiety, in the presence of a β-(1,4)-N-acetylgalactosaminyl-transferase or a mutant thereof, with a non-natural sugar-derivative nucleotide. The non-natural sugar-derivative nucleotide is according to formula (3):

    wherein A is selected from the group consisting of -N 3 ; -C(O)R 3 ; -C=C-R 4 ; -SH; -SC(O)R 8 ; -SC(V)OR 8 , wherein V is O or S; -X wherein X is selected from the group consisting of F, Cl, Br and I; -OS(O) 2 R 5 ; an optionally substituted C 2 - C 24 alkyl group; an optionally substituted terminal C 2 - C 24 alkenyl group; and an optionally substituted terminal C 3 - C 24 allenyl group.
