Biochem/physiol Actions

Releases unsubstituted Ser- and Thr-linked β-Gal-(1→3)-α-GalNAc (Core 1 type O-glycan) from glycoproteins. Substitutions of the disaccharide core with sialic acid, lactosamine (galactose-N-acetyl glucosamine), or fucose will block hydrolysis and prevent the liberation of the oligosaccharide from the protein. Pretreament with glycolytic enzymes to remove substituent saccharides from the O-glycan may be needed prior to cleavage using O-glycosidase..

Packaging

Supplied with 5× Reaction Buffer, 250 mM NaH2PO4 pH 5.0.

Unit Definition

One unit will hydrolyze 1 μmole of p-nitrophenyl galacto-N-bioside (β-Gal-(1→3)-α-GalNAc-1→ΟC6H4NO2) per min at 37 °C at pH 6.5.

Physical form

Solution in 50 mM sodium phosphate, pH 7.5

Analysis Note

Screened for presence of: β-galactosidase, α-mannosidase, β-hexosaminidase, α-fucosidase, neuraminidase, and proteases. See Certificate of Analysis for lot specific information.

Interactions between salivary glycoproteins and many oral bacteria have been shown to depend on O-linked glycans on salivary glycoproteins. Basic proline-rich proteins form the largest group of proteins within human parotid saliva. In the present study human parotid salivary glycoproteins

The common O-glycan core structure in animal glycoproteins is the core 1 disaccharide Galbeta1-3GalNAcalpha1-Ser/Thr, which is generated by the addition of Gal to GalNAcalpha1-Ser/Thr by core 1 UDP-alpha-galactose (UDP-Gal):GalNAcalpha1-Ser/Thr beta1,3-galactosyltransferase (core 1 beta3-Gal-T or T-synthase, EC2.4.1.122). Although O-glycans play important
