. "The yeast oligosaccharyl transferase catalyzes the glycosylation of asparagine residues in secreted, vesicular, and membrane proteins. A complex of at least four membrane-bound polypeptides is responsible for oligosaccharyl transferase activity. Amino acid sequences from the 64 kDa glycoprotein subunit of the complex were used to clone the essential NLT1 (N-linked oligosaccharyl transferase) gene. The Nlt1p gene product is a processed, multiply glycosylated type I membrane protein; it has an extensive amino-terminal soluble domain, a potential hydrophobic transmembrane domain, and a short carboxy-terminal soluble domain. The Nlt1p is significantly similar than the mammalian ribophorin I, a component of the mammalian oligosaccharyl transferase complex, and the enzyme is conserved throughout eukaryotic evolution." . . .
