Substrates: 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

Substrates: 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
