Crystal structure of the Archaeoglobus fulgidus oligosaccharyltransferase (O29867_ARCFU) tethered with an acceptor peptide containing the NVT sequon via a disulfide bond
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 l ...
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.
Archaeal glycosylation protein B long peripheral domain
This domain is found in Archaeal Glycosylation B protein (AglB-Long) in A. fulgidus. When the domain, known as peripheral l (Pl), is combined with the central core (CC) and insertion (IS) sub-units, they form the C-terminal domain. It is thought that ...
This domain is found in Archaeal Glycosylation B protein (AglB-Long) in A. fulgidus. When the domain, known as peripheral l (Pl), is combined with the central core (CC) and insertion (IS) sub-units, they form the C-terminal domain. It is thought that the C-terminal domain may contribute toward the increased thermal stability of the AglB proteins in the hyper-thermophilic [1].
