Structures of the O-linked oligosaccharides of a complex glycoconjugate from Pseudallescheria boydii.

abstract：:In Campylobacter jejuni, the PglB oligosaccharyltransferase catalyzes the transfer of a heptasaccharide from a lipid donor to asparagine within the D/E-X1-N-X2-S/T sequon (X1,2 ≠ P) or releases this heptasaccharide as free oligosaccharides (fOS). Using available crystal structures and sequence alignments, we identifie...
