This is a domain found in the C-terminal region of STT3 present in P. furiosus. STT3 is an Oligosaccharyltransferase which catalyzes the transfer of a heptasaccharide, containing one hexouronate and two pentose residues, onto peptides in an Asn-X-Thr/Ser-motif-dependent manner. This domain, known as the Peripheral 2 (P2) domain, encircles the central core domain [1].	Domain

This is a domain found in STT3 present in P. furiosus. In P. furiousus, STT3 is an Oligosaccharyltransferase which catalyzes the transfer of a heptasaccharide, containing one hexouronate and two pentose residues, onto peptides in an Asn-X-Thr/Ser-motif-dependent manner. This domain is inserted into the central core (CC) domain and hence is referred to as the Insert (IS) domain. This IS domain contains a disulphide bond [1].	Domain

This domain is found in Oligosaccharyl transferase from Pyrococcus furiosus (OST, also known as AglB-L) and similar archaeal sequences. OST catalyses the co-translational transfer of an oligosaccharide from a lipid donor to an asparagine residue in nascent polypeptide chains. This protein is organised into four regions: a N-terminal half (Pfam:PF02516), the central core (CC) domain that includes the IS (insert) domain (Pfam:PF18246) and two peripheral domains, P1 (this entry) and P2 (Pfam:PF18235). This domain, which consists mainly of beta-strands, encircles the central core domain [1].	Domain
