Název v původním jazyce

Analysis of the glycosylation pattern of plant copper amine oxidases by MALDI-TOF/TOF MS coupled to a manual chromatographic separation of glycans and glycopeptides

Popis výsledku v původním jazyce

The N-glycosylation in pea seedling amine oxidase and lentil seedling amine oxidase was analyzed in the present work. For that purpose, the enzymes were purified as native proteins from their natural sources. An enzymatic deglycosylation of pea seedlingamine oxidase by endoglycosidase H under denaturing conditions combined with its proteolytic digestion by trypsin was carried out in order to analyze both N-glycans and trimmed N-glycopeptides with a residual N-acetylglucosamine attached at the originally occupied N-glycosylation sites. The released N-glycans were subjected to a manual chromatographic purification followed by MALDI-TOF/TOF MS. MS and MS/MS analyses were also performed directly on peptides and N-glycopeptides generated by proteolytic digestion of the studied enzymes. Sequencing of glycopeptides by MALDI-TOF/TOF MS/MS after their separation on a RP using a microgradient chromatographic device clearly demonstrated binding of paucimannose and hybrid N-glycan structures at A
