| 英文摘要 | Human serum is a complex body fluid that contains various n-linked and o-linked glycoproteins. compared with n-linked glycoproteins, the serum o-linked glycoproteins are not well-studied due to their high heterogeneity and their low abundance. herein, we presented a novel chemoenzymatic method to analyze core-1 type of o-galnacylation in human serum. in this approach, the tryptic digest of serum was first subjected to pngase f treatment to release the n-glycan and was then treated with strong acid to release sialic acid residues from mucin-type o-glycans. in this way, the internal gal/galnac residues were exposed and were oxidized by the galactose oxidase to carry the aldehyde groups. the oxidized o-galnacylated peptides were then captured by hydrazide beads and eluted with methoxylamine for lc-ms/ms analysis. the de-n-deglycosylation decreased the abundance of n-glycopeptides, the desialylation simplified the o-glycans and the enzymatic oxidization conferred the enrichment specificity. we have demonstrated that this method was fitted to analyze o-galnacylated peptides with high confidence. this method was applied to analyze human serum, which resulted in the identification of 59 o-galnac modified peptide sequences corresponding to 38 glycoproteins from 50 mu l of serum. this method is expected to have broad applications in the analysis of o-glycoproteome. |
