endo-α-N-acetylgalactosaminidase
Cat No.
EXWM-3960
Description
The enzyme catalyses the liberation of Gal-(1→3)-β-GalNAc α-linked to serine or threonine residues of mucin-type glycoproteins. EngBF from the bacterium Bifidobacterium longum specifically acts on core 1-type O-glycan to release the disaccharide Gal-(1→3)-β-GalNAc. The enzymes from the bacteria Clostridium perfringens, Enterococcus faecalis, Propionibacterium acnes and Alcaligenes faecalis show broader specificity (e.g. they can also release the core 2 trisaccharide Gal-(1→3)-β-(GlcNAc-(1→6)-β)-GalNAc or the core 3 disaccharide GlcNAc-(1→3)-β-GalNAc). The enzyme may play an important role in the degradation and utilization of mucins having core 1 O-glycan.
