Abstract: The N-linked glycosylation of secretory and membrane proteins is the most complex posttranslational modification known to occur in eukaryotic cells. It has been shown to play critical roles in modulating protein function. Although this important biological process has been extensively studied in mammals, much less is known about this biosynthetic pathway in plants. The enzymes involved in plant N-glycan biosynthesis and processing are still not well defined and the mechanism of their genetic regulation is almo… Show more

“…The glycopeptides discovered in the digests of the native subunits proved glycosylations on three sites: T7 (AVPVNTSDPLLIDWVR) and T12 (NNTGLVLVYHTK) in the large subunit, and T45 (LFLFNNATDITVK) in the small subunit. Considerable heterogeneity was observed: on T12, typical plant glycosylation types (complex and paucimannosidic, Maia and Leite, 2001;Lerouge et al, 1998) were found [(GlcNAc) 0-2 (Xyl) 0-1 (Fuc) 0-1 (Man) 3 (GlcNAc) 2 ], as well as glycans of which the pentasaccharide core was trimmed [(Xyl) 0-1 (Fuc) 0-1 (Man) 1-3 (GlcNAc) 2 ]. T45 only contained high-mannose type glycosylation [(Man) 0-3 (Man) 3 (GlcNAc) 2 ].…”
