Endo-β-N-acetylglucosaminidase F2

Endo-β-N-acetylglucosaminidase F2 (Endo F2), a highly specific endoglycosidase, cleaves within the chitobiose core of asparagine-linked complex biantennary and high mannose oligosaccharides from glycoproteins and glycopeptides. Endo F2 cleaves biantennary glycans at a rate approximately 20 times greater than high mannose glycans. The activity of Endo F2 is identical on biantennary structures with and without core fucosylation. Endo F2 is not active on hybrid or tri- and tetra-antennary oligosaccharides[1].
