Unlike N-glycans, O-glycans are smaller, highly diverse branched carbohydrate molecules that can attach to various protein structures. This characteristic leads to analytical complexity, making it challenging to analyze O-glycosylation sites. The variability of glycosylation sites is a key indicator of cellular activity, as evidenced by the correlation between reduced attachment of glycosylation sites on serum proteins and the severity of congenital glycosylation disorders (CDGs). Therefore, accurately determining site occupancy is crucial to fully understand the impact of protein glycosylation on human health.
The general steps for O-glycosylation site analysis include proteolytic digestion of glycoproteins, hydrophilic interaction liquid chromatography for enrichment and separation of glycopeptides. Enriched O-glycopeptides can be analyzed using reverse-phase liquid chromatography-ion trap mass spectrometry.
