part of endoplasmic reticulum membrane UDP-N-acetylglucosamine transferase complex https://github.com/geneontology/go-ontology/issues/27981 cellular_component GO:0043541 A multienzyme, heterooligomeric complex involved in dolichyl-linked oligosaccharide synthesis. In yeast the complex is composed of Alg7p, which catalyzes the first step (GlcNAc1-PP-Dol from dolichol-phosphate and UDP-GlcNAc), and Alg13p plus Alg14p, the catalytic and anchoring subunits respectively, which together catalyze the second step (GlcNAc2-PP-dolichol from GlcNAc1-PP-Dol and UDP-GlcNAc) of dolichyl-linked oligosaccharide synthesis. transferase complex, transferring phosphorus-containing groups membrane protein complex endoplasmic reticulum protein-containing complex
