Technique(s) used for Glycosylated Residue(s) Detection Tandem ESI-MS (electrospray ionization quadrupole-TOF mass spectrometry) analysis after chymotrypsin digestion.
Protein Glycosylation- Implication Glucosylation is essential for its bioactivity.
Glycan Information
Glycan Annotation UDP-Glc, UDP-GlcNAc, UDP-Gal, GDP-Man and UDP-Xyl can serve as substrates for SunS GTase but UDP-α-D-glucose is most efficiently used.
Technique(s) used for Glycan Identification GC-MS (gas chromatography-mass spectrometry) analysis after trimethylsilylation
Protein Glycosylation linked (PGL) gene(s)
OST ProGT IDProGT47
Characterized Accessory Gene(s)SunS is a glycosyltransferase with very relaxed substrate specificity. It shows strong regioselectivity and chemoselectivity for glycosylation of a thiol.
Additional CommentS-linked glycosylation is very rare. It has been observed that cysteine glycosylation leads to the formation of more stable products (both at low and high pH) than does serine glycosylation.
