Protein
Bifunctional protein GlmU
Gene
glmU, BMEII0684
Organism
Brucella melitensis biotype 1 (strain 16M / ATCC 23456 / NCTC 10094)
Status
Reviewed - Annotation score: 5 out of 5 - Protein inferred from homologyi

Functioni

Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-N-acetylglucosamine (UDP-GlcNAc). The C-terminal domain catalyzes the transfer of acetyl group from acetyl coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N-acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into UDP-GlcNAc by the transfer of uridine 5-monophosphate (from uridine 5-triphosphate), a reaction catalyzed by the N-terminal domain By similarity.UniRule annotation

Catalytic activityi

Acetyl-CoA + alpha-D-glucosamine 1-phosphate = CoA + N-acetyl-alpha-D-glucosamine 1-phosphate.UniRule annotation
UTP + N-acetyl-alpha-D-glucosamine 1-phosphate = diphosphate + UDP-N-acetyl-alpha-D-glucosamine.UniRule annotation

Cofactori

Binds 1 magnesium ion per subunit By similarity.UniRule annotation
