CRYSTAL STRUCTURE OF THE COMPLEX OF ENDO-BETA-N-ACETYLGLUCOSAMINIDASE F3 WITH A BIANTENNARY COMPLEX OCTASACCHARIDE

Released:

Function and Biology Details

Reaction catalysed:
Endohydrolysis of the N,N'-diacetylchitobiosyl unit in high-mannose glycopeptides and glycoproteins containing the -(Man(GlcNAc)(2))Asn- structure. One N-acetyl-D-glucosamine residue remains attached to the protein, the rest of the oligosaccharide is released intact.
