[https://www.uniprot.org/uniprot/GLMU_MYCTU GLMU_MYCTU] 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.<ref>PMID:19237750</ref> <ref>PMID:19121323</ref>

Antibiotic resistance is a major issue in the treatment of infectious diseases such as tuberculosis. Existing antibiotics target only a few cellular pathways and there is an urgent need for antibiotics that have novel molecular mechanisms. The glmU gene is essential in Mycobacterium tuberculosis, being required for optimal bacterial growth, and has been selected as a possible drug target for structural and functional investigation. GlmU is a bifunctional acetyltransferase/uridyltransferase that catalyses the formation of UDP-GlcNAc from GlcN-1-P. UDP-GlcNAc is a substrate for two important biosynthetic pathways: lipopolysaccharide and peptidoglycan synthesis. The crystal structure of M. tuberculosis GlmU has been determined in an unliganded form and in complex with GlcNAc-1-P or UDP-GlcNAc. The structures reveal the residues that are responsible for substrate binding. Enzyme activities were characterized by (1)H NMR and suggest that the presence of acetyl-coenzyme A has an inhibitory effect on uridyltransferase activity.
