Bacteriol. 189:3680-3681(2007). 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: 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:0000255|HAMAP-Rule:MF_01631}; 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:0000255|HAMAP-Rule:MF_01631}; CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; CC Evidence={ECO:0000255|HAMAP-Rule:MF_01631}; CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01631}; 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.
