CC -!- FUNCTION: Catalyzes the initial step of dolichol-linked oligosaccharide
CC biosynthesis in N-linked protein glycosylation pathway: transfers
CC GlcNAc-1-P from UDP-GlcNAc onto the carrier lipid dolichyl phosphate
CC (P-dolichol), yielding GlcNAc-P-P-dolichol.
CC {ECO:0000250|UniProtKB:Q9H3H5}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a dolichyl phosphate + UDP-N-acetyl-alpha-D-glucosamine = N-
CC acetyl-alpha-D-glucosaminyl-diphosphodolichol + UMP;
CC Xref=Rhea:RHEA:13289, Rhea:RHEA-COMP:9517, Rhea:RHEA-COMP:9519,
CC ChEBI:CHEBI:57683, ChEBI:CHEBI:57705, ChEBI:CHEBI:57865,
CC ChEBI:CHEBI:58427; EC=2.7.8.15;
CC Evidence={ECO:0000250|UniProtKB:Q9H3H5};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q9H3H5};
CC -!- ACTIVITY REGULATION: Activated by mannosylphosphoryldolichol and
CC phospholipids such as phosphatidylglycerol and phosphatidylcholine.
CC Inhibited by natural nucleoside antibiotic tunicamycin, which acts as a
CC structural analog and competitor of UDP-GlcNAc.
CC {ECO:0000250|UniProtKB:Q9H3H5}.
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC {ECO:0000250|UniProtKB:Q9H3H5}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q9H3H5}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q9H3H5}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:Q9H3H5}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 4 family. {ECO:0000305}.
