Facts (generated by robot; please edit if you find it inaccurate)
- Specific Activity One unit of O-Glycosidase is defined as the amount of enzyme required to produce 1 mole of p-nitrophenol (pNP) in 1 minute at 37C, pH 5.
- However, it should be noted that the specificity of O-glycosidase is limited to cleaving only the disaccharide unit Gal-[beta](1-3)-GalNAc from O-linked oligosaccharides (9) and thus may not cleave the types of O-linked glycans that might be present on gO.
- O-Glycosidase is known to cleave only glycans which contain the mucin-type core 1 structure Gal[beta]1-3GalNAc[alpha]1-Ser/Thr.
- As O-glycosidase is known not to tolerate any substitution on Gal or on GalNAc, gp40 was desialylated prior to incubation with O-glycosidase treatment.
- 13 Da), on the serine/threonine residues before, but not after, treatment with Endo-O-glycosidase is useful in identifying O-glycan sites.
