The N-terminal domain of N-Acetylglucosamine-1-phosphate uridyltransferase (GlmU). GlmU is an essential bacterial enzyme with both an acetyltransferase and an uridyltransferase activity which have been mapped to the C-terminal and N-terminal domains, respectively. This family represents the N-terminal uridyltransferase. GlmU performs the last two steps in the synthesis of UDP-N-acetylglucosamine (UDP-GlcNAc), which is an essential precursor in both the peptidoglycan and the lipopolysaccharide metabolic pathways in Gram-positive and Gram-negative bacteria, respectively.
