Protein Domain : Oligosaccharyl transferase, archaeal IPR026410

Type	Family
Description	This entry represents the archaeal oligosaccharyl transferases. Members of this protein family are found, one to three members per genome, in the same species of Euryarchaeota that contain the predicted protein-sorting enzyme archaeosortase and its cognate protein-sorting signal PGF-CTERM [ ]. Oligosaccharyl transferase AglB (STT3) is responsible for transferring a pentasaccharide moiety to at least two S-layer glycoproteinsites in Haloferax volcanii [ ]. Dolichyl-phosphooligosaccharide-protein glycotransferase 3 (aglB3) from Archaeoglobus fulgidus is required for the first step in attaching an N-linked-carbohydrate to a newly-synthesized protein, by transfering a glycan from the lipid carrier dolichol-monophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif [].
