| Technique(s) used for Glycosylation Detection | Mass shift detected on SDS-polyacrylamide gel and glycan identification by nano-LC-MS/MS |
| Technique(s) used for Glycosylated Residue(s) Detection | Nano-LC-MS/MS (nano-liquid chromatography-electrospray tandem mass spectrometry) |
| Protein Glycosylation- Implication | The glycans on flagellin proteins are involved in the flagella assembly process. |
| Glycan Information |
| Glycan Annotation | Linkage:β-GlcNAc-Asn.
Trisaccharide (779 Da) composed ofβ-Manp NAcA6Thr-(1- 4)-β-Glcp NAc3NAcA-(1-3)-β-Glcp NAc. The sugars are mannuronic acid with the attached threonine, diacetylated glucuronic acid, N-acetylglucosamine.
In a second version of this strain (M. voltae PS*), the glycan is modified with one additional residue (either 220 or 262 Da) linked to the terminal modified mannuronic acid. |
| BCSDB ID | 10182 |
| GlyTouCan | G47369PB |
| Technique(s) used for Glycan Identification | NanoLC-MS/MS analysis and NMR spectroscopy-COSY (correlated spectroscopy), TOCSY (total correlation spectroscopy), NOESY (nuclear Overhauser effect spectroscopy) spectra, and 1H-13C HMBC (heteronuclear multiple bond coherence) spectra. |
| Protein Glycosylation linked (PGL) gene(s) |
| OST Gene Name | AglB |
| OST ProGT ID | ProGT16 |
| Characterized Accessory Gene(s) | AglH, AglC, AglK, AglA glycosyltransferases are involved in the biosynthesis of the glycan. AglH is a GlcNAc-1-phosphate transferase transfering first sugar to dolichol pyrophosphate. AglC and AglK add the second sugar residue and AglA adds the third sugar to the glycan.
Characterized by gene deletion studies |
| Accessory Gene(s)Progt ID | ProGT16.1, ProGT16.2, Pro |
| Additional Comment | Post translational modification was detected in the year 1999. It was confirmed as glycosylation (by identifying the glycans) in 2005. |
