Summary
GlmU contains 22 hexapeptide repeats. [More information is available at EcoGene: EG11198]. glmU encodes a fused enzyme with two enzymatic activities that catalyze sequential steps in the biosynthesis of UDP-N-acetyl-D-glucosamine (UDP-GlcNAc), an essential precursor of cell wall peptidoglycan, lipopolysaccharide and enterobacterial common antigen . [More information is available at EcoCyc: EG11198].
