Online Resource 5 ESI-MS spectrum of underivatized N-glycans from PHB-01seed, released by digestion with Nglycosidase A (PNGase A). All m/z signals correspond to the [M+Na]+ adduct. N-glycan representations follow the
conventions of Harvey et al. (2009). Monosaccharide composition was represented as (Man.GlcNAc.Fuc.Xyl).
GlcNAc: N-acetylglucosamine, Man: mannose, Fuc: fucose, Xyl: xylose
