| EMBL CDS | CAL35243.1 |
| Sequence length | 713 AA |
| Subcellular Location | Membrane (Integral component of membrane) |
| Function in Native Organism | 1) The PglB is OSTase which transfer an heptasaccharide to N of D/E-N-X-T/S consensus sequence of the protein in Campylobacter jejuni. |
| String | 192222.Cj1126c. |
| Potential Application | 1) PglB can be used to create artificial glycopeptides because it has relaxed substrate specificity of accepting peptide substrates over the full-length protein.
2) PglB can transfer undecaprenyl pyrophosphate-linked saccharides of various lengths (2?7 saccharides) adds to the promise of using PglB in the synthesis of diverse glycopeptide products. |
| Additional Information | 1) PglB requires an acetamido group at the C-2.
2) R331 of C.lari and R328 of C.jejuni form a salt bridge with acidic amino acid.
3) PglB can transfer several structurally different O-antigen saccharides to protein.
