Oxonium ion glycan
WebJan 1, 2016 · The oxonium ion-containing spectra were matched to the N-glycopeptide candidate database (comprising the identified N-glycan and glycosite-containing peptides) to assign all glycopeptide ... WebThe presence of the oxonium ion derived from the glycan in the HCD spectra (e.g., HexNAc, 204.09 m / z) should enable more advanced workflows to be employed for the characterization of glycopeptides ( Wu et al., 2007; Scott et al., 2011 ).

Accurate mass measurement of the glycan oxonium ions in selected glycopeptide MS/MS spectra was achieved by using a number of the neighboring peptide fragment ions as internal mass standards. Plausi-ble elemental formulas were then generated for each glycan greatly …
WebMar 1, 2024 · Distinguishing the correct glycan from spectra in which oxonium ions seem to indicate an alternative composition is indeed a challenging problem, even for expert manual curation of glycan assignments. Maintaining a 1% entrapment glycan rate despite this extensive cofragmentation is thus an impressive achievement for our method.
