Protein Glycosylation- ImplicationNo specifc role has been proposed for O-linked oligosaccharides in chondrotinase AC but their positioning and interaction in the structure of chondroitinase AC in the case of Ser455 attached oligosaccharide, presents a possibility for some role in protein folding, as in mammalian systems.
Glycan Information
Glycan AnnotationLinkages: Man-Ser.
The approx. weights of glycans attached to S328 and S455 were 1190Da and 1080 Da, respectively.
Branched heptasaccharide is: galactose-β(1–4)[galactose-α(1–3)](2-O-Me)fucose-β(1–4)xylose-β (1–4)glucuronic acid-α(1–2)[rhamnose-α(1–4)]mannose-α(1-O)Ser.
Only tetrasaccharide glycan observed in crystal structure: Man-(Rha)-GlcUA-Xyl (xylose-β (1–4)glucuronic acid-α(1–2)[rhamnose-α(1–4)]mannose-α(1-O)Ser.
