摘要
Protein glycosylation,one of the most common post-translational modifications,is implicated in the occurrence and development of many diseases.The biological functions of glycopeptides are realized by the collaborative effects of both the sugar structure and peptide sequence.However,due to the complexity and diversity of glycopeptides,it is difficult to obtain a wide range of structurally well-defined glycopeptides for biofunctional studies and development of glycopeptide-based drugs.
