CC -!- FUNCTION: Catalyzes the last two sequential reactions in the de CC novo biosynthetic pathway for UDP-N-acetylglucosamine (UDP- CC GlcNAc). The C-terminal domain catalyzes the transfer of acetyl CC group from acetyl coenzyme A to glucosamine-1-phosphate (GlcN-1-P) CC to produce N-acetylglucosamine-1-phosphate (GlcNAc-1-P), which is CC converted into UDP-GlcNAc by the transfer of uridine 5- CC monophosphate (from uridine 5-triphosphate), a reaction catalyzed CC by the N-terminal domain. {ECO:0000256|HAMAP-Rule:MF_01631, CC ECO:0000256|SAAS:SAAS00381483}.
