CC -!- FUNCTION: Catalyzes the last two sequential reactions in the de novo
CC biosynthetic pathway for UDP-N-acetyl-glucosamine (UDP-GlcNAc).
CC Responsible for the acetylation of GlcN-1-P to GlcNAc-1-P, and for the
CC uridyl transfer from UTP to GlcNAc-1-P, to produce UDP-GlcNAc and
CC pyrophosphate. {ECO:0000256|ARBA:ARBA00024726}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + N-acetyl-alpha-D-glucosamine 1-phosphate + UTP =
CC diphosphate + UDP-N-acetyl-alpha-D-glucosamine; Xref=Rhea:RHEA:13509,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:33019, ChEBI:CHEBI:46398,
CC ChEBI:CHEBI:57705, ChEBI:CHEBI:57776; EC=2.7.7.23;
CC Evidence={ECO:0000256|ARBA:ARBA00001851};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + alpha-D-glucosamine 1-phosphate = CoA + H(+) + N-
CC acetyl-alpha-D-glucosamine 1-phosphate; Xref=Rhea:RHEA:13725,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57287, ChEBI:CHEBI:57288,
CC ChEBI:CHEBI:57776, ChEBI:CHEBI:58516; EC=2.3.1.157;
CC Evidence={ECO:0000256|ARBA:ARBA00000731};
CC -!- PATHWAY: Nucleotide-sugar biosynthesis; UDP-N-acetyl-alpha-D-
CC glucosamine biosynthesis; N-acetyl-alpha-D-glucosamine 1-phosphate from
CC alpha-D-glucosamine 6-phosphate (route II): step 2/2.
CC {ECO:0000256|ARBA:ARBA00005166}.
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 {ECO:0000256|ARBA:ARBA00005208}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the transferase
CC hexapeptide repeat family. {ECO:0000256|ARBA:ARBA00007707}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the N-
CC acetylglucosamine-1-phosphate uridyltransferase family.
CC {ECO:0000256|ARBA:ARBA00007947}.
