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:0000256|HAMAP-Rule:MF_01631}.
