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.

STT3 is part of the oligosccharyl transferase (OTase) complex and required for its activity, which transfers a lipid-linked core-oligosaccharide to selected asparagine residues in the ER. In the archaea STT3 occurs alone, rather than in an OTase complex, and is required for N-glycosylation of asparagines [1-5]. This is a globular domain which adopts a mixed alpha/beta fold and contains the highly conserved WWDYG motif, in which the aspartate residue is thought to function as a catalytic residue [1-5].
