Title : Human
urokinase contains
GalNAc beta (1-4)[Fuc alpha (1-3)]GlcNAc beta (1-2) as a novel terminal element in
N-linked carbohydrate chains
Abstract :
- Structural analysis of enzymically released N-linked carbohydrate chains of human urokinase (urinary-type plasminogen activator) by 1H NMR spectroscopy and FAB-MS demonstrated that the N-linked oligosaccharides on the only N-glycosylation site contain diantennary structures with the novel GalNAc beta (1-4) [Fuc alpha (1-3)]GlcNAc beta (1-2) element in the upper or the lower branch
