| Abstract: | Protein glycosylation is critical since it connects complex metabolic pathways to diverse proteoforms, fine-tunes protein structures and exerts biological functions. Aberrant glycosylation on the other hand is associated with many diseases, including cancers, inflammation and metabolic disorders. By resolving monosaccharide residues on intact glycoprotein complexes, native mass spectrometry can shed light on glycan heterogeneity, glycoprotein structure and molecular recognition. Here, we focus on the two most prevalent forms of glycosylation, namely N- and O- linked, and discuss recent progress in native mass spectrometry for elucidating glycoprotein structural heterogeneity and relating specific glycan repertoires to glycoprotein interactions. |
