Subcellular LocationSurface
Function In Archaea, which do not possess other cell wall components, the S-layer has to maintain the cell integrity and stabilize as well as to protect the cell against mechanical and osmotic stresses or extreme pH conditions. It is also predicted that the S-layer has to maintain or even determine the cell shape.
Glycosylation Status
Glycosylation Type N- (Asn) linked

Protein Glycosylation- Implication Mutations that ultimately alter the structure of the S-layer protein could affect the protein interaction and disrupt the structural integrity of the cell. As a result, such mutants could suffer serious cell stability problems. It is this effect on the S-layer that likely explains why the agl mutants are so unstable.
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 NameAglB
OST ProGT IDProGT16
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.
