Technique(s) used for Glycosylation DetectionDeglycosylation (trifluoromethanesulfonic acid), aberrant migration on SDS-PAGE.
Technique(s) used for Glycosylated Residue(s) Detection Protease digestion and glycopeptide separation by molecular sieve chromatography and reversed-phase HPLC. Deglycosylated and undeglycosylated peptides were run on 2D PAGE and subjected to N-terminal sequencing post blotting.
Protein Glycosylation- Implication An N terminal SLH sequence of A. kivui S-layer glycoprotein is suggested to fold independently and present itself in a modular way that may serve as an anchor to the peptidoglycan. Glycosylated residues are surface exposed and implicated in protease K resistance.
Glycan Information
Glycan Annotation Carbohydrate content 8% corresponding to 40 to 50 sugar molecules per protein monomer. Acidic, repetitive heterogenous glycans of varying length containing N-acetylglucosamine, 1,6 linked glucose, 1,4 linked galactosamine and/or unidentified sugar-related component.
Technique(s) used for Glycan Identification Hydrazinolysis followed by amino-acid analysis as well as two-dimensional NMR spectroscopy
Protein Glycosylation linked (PGL) gene(s)
Additional CommentA new recognition sequence for tyrosine linked glycosylation in A. kivui is suggested based on the fact that all glycosylated tyrosine in the sequence are preceded by valine.
