| Sequence length | 56 AA |
| Subcellular Location | Secreted |
| Function | SPβ prophage-derived bacteriocin sublancin-168. It has antimicrobial activity against Gram-positive bacteria. It is stable at both low and high pH and lacks free thiols. |
| Protein Structure | |
| PDB ID | 2MIJ |
| Glycosylation Status | |
| Glycosylation Type | S- (Cys) linked |
| Experimentally Validated Glycosite(s) in Full Length Protein | (Propeptide: 1-19) C41 |
| Experimentally Validated Glycosite(s ) in Mature Protein | C22 |
| Glycosite(s) Annotated Protein Sequence | >sp|P68577|SUNA_BACSU SPBc2 prophage-derived bacteriocin sublancin-168 OS=Bacillus subtilis GN=sunA PE=1 SV=1 MEKLFKEVKLEELENQKGSGLGKAQCAALWLQCASGGTIGC*(41)GGGAVACQNYRQFCR |
| Sequence Around Glycosites (21 AA) | LQCASGGTIGCGGGAVACQNY |
| Technique(s) used for Glycosylation Detection | Higher mass observed using mass spectrometry |
| 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-β-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 ID | ProGT46 |
| 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 Comment | S-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. |
