Releases non-reducing terminal β(1-2,3,4,6)-linked N-acetylglucosamine (GlcNAc) and N-acetylgalactosamine (GalNAc) residues.
The enzyme exhibits a broad specificity, cleaving non-reducing terminal β(1-2,3,4,6)-linked N-acetylglucosamine (GlcNAc) and N-acetylgalactosamine (GalNAc) residues. This enzyme is very useful in the study of isolated glycans, glycolipids and glycoproteins, especially in combination with β N-acetylhexosaminidase from S. pneumoniae (GK80050).
We also offer this enzyme at a higher concentration - see GKX-5023. Higher enzyme concentrations may be necessary to remove bisecting β(1-4)-linked GlcNAc residues in complex N-glycans.

Useful for the structural analysis of isolated glycans and glycoconjugates.
