英文摘要enrichment of glycopeptides by hydrazide chemistry (hc) is a popular method for glycoproteomics analysis. however, possible side reactions of peptide backbones during the glycan oxidation in this method have not been comprehensively studied. here, we developed a proteomics approach to locate such side reactions and found several types of the side reactions that could seriously compromise the performance of glycoproteomics analysis. particularly, the hc method failed to identify n-terminal ser/thr glycopeptides because the oxidation of vicinal amino alcohol on these peptides generates aldehyde groups and after they are covalently coupled to hc beads, these peptides cannot be released by pngase f for identification. to overcome this drawback, we apply a peptide n-terminal protection strategy in which primary amine groups on peptides are chemically blocked via dimethyl labeling, thus the vicinal amino alcohols on peptide n-termini are eliminated. our results showed that this strategy successfully prevented the oxidation of peptide n-termini and significantly improved the coverage of glycoproteome.
