|RESID Database - Table of Glycosylation Modifications|
1 The glycosylation of Ser by xylose (Xyl) was reported in a yeast protein but was not supported by any chemical evidence. That report is documented as a deprecated modification in AA0406. The attachment of chondroitin sulfate, dermatan, heparan, and keratan by xylose linker tetrasaccharides are documented in AA0208, AA0209, AA0210, and AA0247.
2A modification that is probably Ser glycosylation by glucuronic acid (GlcA) is documented in AA0291.
