This entry consists of the oligosaccharyl transferase STT3 subunit and related proteins. The STT3 subunit is part of the oligosaccharyl transferase (OTase) complex of proteins and is required for its activity [2]. In eukaryotes, OTase transfers a lipid-linked core-oligosaccharide to selected asparagine residues in the ER [2]. In the archaea STT3 occurs alone, rather than in an OTase complex, and is required for N-glycosylation of asparagines [3-4]. This entry represents the N-terminal domain, consisting of transmembrane helices.	Domain

This entry represents the third domain of eukaryotic Ribophorin II (RPN2) proteins. The mammalian oligosaccharyltransferase (OST) is a protein complex that effects the cotranslational N-glycosylation of newly synthesised polypeptides, and is composed of the following proteins: ribophorins I and II (RI and RII), OST48, and Dadl, N33/IAP, OST4, STT3. The family also includes the SWP1 protein from yeast. In yeast the oligosaccharyltransferase complex is composed 7 or 8 subunits, SWP1, being one of them [2][3].	Domain

This entry represents the middle domain (MD) of OST48 from animals and its orthologue from yeast Wbp1 [1,2]. OST48/Wbp1 is a subunit of the oligosaccharyl transferase (OST) complex that catalyses the initial transfer of a defined glycan (Glc3Man9GlcNAc2 in eukaryotes) from the lipid carrier dolichol-pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation [1,2]. This domain adopts a beta-sandwich fold, which together with the N-terminal domain (Pfam:PF03345), interacts with riphophorin II/Swp1 subunit [3].	Domain

Members of this entry are involved in asparagine-linked protein glycosylation. In particular, dolichyl-diphosphooligosaccharide-protein glycosyltransferase (DDOST), also known as oligosaccharyltransferase, transfers the high-mannose sugar GlcNAc(2)-Man(9)-Glc(3) from a dolichol-linked donor to an asparagine acceptor in a consensus Asn-X-Ser/Thr motif. In most eukaryotes, the DDOST complex is composed of three subunits, which in humans are described as a 48kD subunit, ribophorin I, and ribophorin II. However, the yeast DDOST appears to consist of six subunits (alpha, beta, gamma, delta, epsilon, zeta). The yeast beta subunit is a 45kD polypeptide, previously discovered as the Wbp1 protein, with known sequence similarity to the human 48kD subunit and the other orthologues. This is the N-terminal domain of OST48 subunits from animals and plants and the orthologue from yeast Wbp1. This domain is distantly related to the IFT52 N-terminal domain (Pfam:PF23355).	Domain
