Abstract:
The present invention relates to a process for the enzymatic modification of a glycoprotein. The process comprises the step of contacting a glycoprotein comprising a glycan comprising a terminal GlcNAc-moiety, in the presence of glycosyltransferasethat is,or is derived from,a β-(1,4)-N-acetylgalactosaminyltransferase, with anon-natural sugar-derivative nucleotide. Thenon-natural sugar-derivative nucleotide is according to formula (3): wherein A is selected from the group consisting of -N 3 , -C(O)R 3 , -(CH 2 ) i C≡C-R 4 , - SH, -SC(O)R 8 , -SC(0)OR8, -SC(S)OR8, -F, -CI, -Br -I, -OS(O) 2 R 5 , terminal C 2 - C 24 alkenyl groups, C 3 - C 5 cycloalkenyl groups, C 4 - C 8 alkadienyl groups, terminal C 3 - C 24 allenyl groups and amino groups. The invention further relates to a glycoprotein obtainable by the process according to the invention, to a bioconjugate that can be obtained by conjugating the glycoprotein with a linker-conjugate, and to β-(1,4)-Ν- acetylgalactosaminyltransferases that can be used in preparing the the glycoprotein according to the invention.
