We have isolated an endo-beta-galactosidase designated E-ABase from Clostridium perfringens ATCC 10543 capable of liberating both the A trisaccharide (A-Tri; GalNAcalpha1-->3(Fucalpha1-->2)Gal) and B trisaccharide (B-Tri; Galalpha1-->3(Fucalpha1-->2)Gal) from glycoconjugates containing blood group A and B glycotopes, respectively. We have subsequently cloned

The unique clostridial endo-beta-galactosidase (Endo-beta-Gal(GnGa)) capable of releasing the disaccharide GlcNAc alpha 1,4Gal from O-glycans expressed in the gastric gland mucous cell-type mucin has been crystallized. The crystal belongs to space group P6(3), with unit-cell parameters a = 160.4, c

Capillary liquid chromatography-mass spectrometry using graphitised carbon stationary phase and ion trap mass spectrometry was shown to be a powerful technique for analysing glycosaminoglycans digested with endoglycosidases. Commonly found disaccharides from heparin/heparan sulphate digests at sub nanomole levels were found
