General description

A dabsylated tetrapeptide with the N-glycan having the asialo-, agalacto-substructure of biantennary N-linked oligosaccharides found in a wide range of glycoproteins.

Substitution of the asparagine-linked GlcNAc by alpha1,3-linked fucose is a widespread feature of plant as well as of insect glycoproteins, which renders the N-glycan immunogenic. We have purified from mung bean seedlings the GDP-L-Fuc:Asn-linked GlcNAc alpha1,3-fucosyltransferase (core alpha1,3-fucosyltransferase) that is
