Posttranslational Modification

Posttranslational Modification Comment Organism
glycoprotein all four potential N-glycosylation sites are subjected to glycosylation and are occupied by oligomannosidic structures with Man5GlcNAc2 as the main oligosaccharide, found on the majority of TGG1 glycopeptides. In addition, Man6GlcNAc2, Man7GlcNAc2 and Man8GlcNAc2 are also present on several glycosylation sites, while on Asn108 the predominant peak corresponds to Man9Glc-NAc2. TGG2 N-glycans are not altered in the mvp1 mutant Arabidopsis thaliana
glycoprotein all nine potential N-glycosylation sites are subjected to glycosylation and are occupied by oligomannosidic structures with Man5GlcNAc2 as the main oligosaccharide, found on the majority of TGG1 glycopeptides. In addition, Man6GlcNAc2, Man7GlcNAc2 and Man8GlcNAc2 are also present on several glycosylation sites, while on Asn108 the predominant peak corresponds to Man9Glc-NAc2. TGG1 from mns mutants displays incompletely processed oligomannosidic N-glycans, while TGG1 N-glycans are not altered in the mvp1 mutant Arabidopsis thaliana
