摘要：

This work demonstrates that (N-acetyl[C-14]glucosamine)2 is transferred from dolichyl pyrophosphate - (N-acetyl[C-14]glucosamine)2 to endogenous nuclear glycoproteins. The (N-acetyl[C-14]glucosamine)2 moiety is N-linked, since it can be released from the tryptic glycopeptides by N-glycosidase F and by hydrazinolysis, but not by beta-elimination. The biological significance of this direct transfer of N, N'-diacetylchitobiose to nuclear proteins remains to be elucidated.
