Subcellular LocationMembrane (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.
String192222.Cj1126c.
Potential Application1) 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 Information1) 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.
