Releases non-reducing terminal β(1-2,3,4,6)-linked N-acetylglucosamine (GlcNAc) and N-acetylgalactosamine (GalNAc) residues. Supplied at a higher concentration than GKX-5003. Higher enzyme concentrations may be necessary to remove bisecting β(1-4)-linked GlcNAc residues in complex N-glycans.
The enzyme exhibits a broad specificity, cleaving non-reducing terminal β(1-2,3,4, and 6)-linked-N-acetylglucosamine (GlcNAc) and N-acetylgalactosamine (GalNAc) residues. It has proved very useful in the study of isolated glycans, glycolipids and glycoproteins, especially in combination with β-N-Acetylhexosaminidase from S. Pneumoniae (GK80050).
