CC   -!- FUNCTION: Catalyzes the last two sequential reactions in the de novo
CC       biosynthetic pathway for UDP-N-acetylglucosamine (UDP-GlcNAc). The C-
CC       terminal domain catalyzes the transfer of acetyl group from acetyl
CC       coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N-
CC       acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into
CC       UDP-GlcNAc by the transfer of uridine 5-monophosphate (from uridine 5-
CC       triphosphate), a reaction catalyzed by the N-terminal domain.
CC       {ECO:0000255|HAMAP-Rule:MF_01631}.
CC   -!- CATALYTIC ACTIVITY:
