| Technique(s) used for Glycosylation Detection | Rapid migration on SDS-PAGE after chemical deglycosylation with TFMS, glycoprotein staining using GelCode? glycoprotein staining kit. |
| Technique(s) used for Glycosylated Residue(s) Detection | Site-directed mutagenesis and MALDI-TOF MS (matrix assisted laser desorption/ionization time of flight mass spectrometry) analysis |
| Protein Glycosylation- Implication | The flagellin glycan structures have a role to play in the virulence and host specificity of P. syringae. Glycosylation is important for the HR-inducing (hypersensitive reaction, a rapid and strong plant defence response) ability of the flagellin in plants. |
| Glycan Information |
| Glycan Annotation | Linkage: Rha-Ser.
S201 carries a unique trisaccharide consisting of two rhamnosyl (Rha) residues and one modified 4-amino-4,6-dideoxyglucosyl (Qui4N; named as viosamine) residue, ß-D-Quip4N(3-hydroxy-1-oxobutyl)2Me-(1?3)-?-L-Rhap-(1?2)-?-L-Rhap. The trisaccharide is present as the major glycan on each Ser residue. The glycans contain both L-Rha and D-Rha at a molar ratio of about 4:1.
Heterogeneity due to the addition of one or two units of mass value 147 is also observed. |
