to investigate the substrate specificity of PglB, the transfer of a set of lipid-linked polysaccharides in Escherichia coli and Salmonella enterica serovar typhimurium is tested. A hexose linked to the C-6 of the monosaccharide at the reducing end does not inhibit the transfer of the O antigen to the acceptor protein. PglB requires an acetamido group at the C-2. A model for the mechanism of PglB involving this functional group is proposed. Eukaryotic and prokaryotic OTases catalyze the transfer of oligosaccharides by a conserved mechanism. Substitution at the C-6 position in the reducing end of the oligosaccharide does not prevent its PglB-mediated transfer to the protein acceptor AcrA. PglB transferrs a polysaccharide that is assembled by a Wzy-protein-independent pathway. An N-acetyl group in position 2 of the sugar directly linked to the undecaprenyl diphosphate carrier is necessary for recognition and/or catalysis

model glycoprotein carboxypeptidase Y. STT3 from Leishmania is able to complement stt3 deficiency in yeast during vegetative growth, but only poorly during sporulation. Transfers efficiently shortened lipid-linked-mannose oligosaccharides. The Leishmania STT3 homolog is functional mainly as a free enzyme with a broad specificity for the glycosyl donor. When incorporated into the OST complex, it accepts the common Glc3Man9GlcNAc2-PP-Dol donor. Three out of the four STT3 paralogs are able to functionally complement not only an stt3 mutant but also ost1, ost2, wbp1, or swp1 mutants

six different subunits are detected in the wild-type complex, including Stt3p, Ost1p, Wbp1p, Swp1p, Ost3p, and Ost6p. The small 3.4-kDa subunit Ost4p is required for the incorporation of either Ost3p or Ost6p into the complex, resulting in two, functionally distinct OTase complexes in vivo. Ost3p and Ost6p are not absolutely required for OTase activity, but modulate the affinity of the enzyme toward different protein substrates
additional information
the eukaryotic oligosaccharyltransferase is a complex of multiple non-identical subunits. The Yeast oligosaccharyltransferase enzyme complex contains a single Stt3 subunit
