a total of 13 oligosaccharides ranging in size from di- to tetradecasaccharides are identified. Oligosaccharides are composed of repeating unsaturated uronic acid (DELATA UA)-GalNAc disaccharide subunits, with up to the equivalent of one sulfate per disaccharide. Two types of oligosaccharide structures are identified: the first type has an even number of saccharide residues with DELTA(UA) at the nonreducing end and GalNAc at the reducing end and the second type is composed of an odd number of residues with UA at the reducing terminus. Number of sulfates associated with the oligosaccharides increases with the size of the oligosaccharide, up to the equivalent of one sulfate per disaccharide |

liquid chromatography-mass spectrometry is applied to determine the action pattern of different chondroitin lyases: products of chondroitinase ABC from Proteus vulgaris and chondroitinase AC from Flavobacterium heparinum contain unsaturated oligosaccharides of sizes ranging from disaccharide to decasaccharide, demonstrating that both are endolytic enzymes |
