CC -!- FUNCTION: Catalyzes the last two sequential reactions in the de CC novo biosynthetic pathway for UDP-GlcNAc. Responsible for the CC acetylation of Glc-N-1-P to give GlcNAc-1-P and for the uridyl CC transfer from UTP to GlcNAc-1-P which produces UDP-GlcNAc (By CC similarity). CC -!- CATALYTIC ACTIVITY: Acetyl-CoA + alpha-D-glucosamine 1-phosphate = CC CoA + N-acetyl-alpha-D-glucosamine 1-phosphate. CC -!- CATALYTIC ACTIVITY: UTP + N-acetyl-alpha-D-glucosamine 1-phosphate CC = diphosphate + UDP-N-acetyl-D-glucosamine. CC -!- COFACTOR: Binds 1 magnesium ion per subunit (By similarity). CC -!- PATHWAY: Nucleotide-sugar biosynthesis; UDP-N-acetyl-alpha-D- CC glucosamine biosynthesis; N-acetyl-alpha-D-glucosamine 1-phosphate CC from alpha-D-glucosamine 6-phosphate (route II): step 2/2. CC -!- PATHWAY: Nucleotide-sugar biosynthesis; UDP-N-acetyl-alpha-D- CC glucosamine biosynthesis; UDP-N-acetyl-alpha-D-glucosamine from N- CC acetyl-alpha-D-glucosamine 1-phosphate: step 1/1. CC -!- PATHWAY: Bacterial outer membrane biogenesis; LPS lipid A CC biosynthesis. CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: In the N-terminal section; belongs to the N- CC acetylglucosamine-1-phosphate uridyltransferase family. CC -!- SIMILARITY: In the C-terminal section; belongs to the transferase CC hexapeptide repeat family.
