Background: N-Acetyl-D-Glucosamine Kinase/NAGK

N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid (MurNAc) are repeating sugar units of peptidoglycan, the major component of bacterial cell wall structure and a drug target of various antibiotics including penicillin (1). Recently, interest has been generated regarding cell wall peptidoglycan catabolism, because as much as 50% of the peptidoglycan is turned over in one generation of bacterial growth (2). N-acetylglycosamine kinase (nagK) is a key enzyme for the recycling of GlcNAc in E. coli (3). Due to its high activity, it can be used for efficient conversion of GlcNAc to GlcNAc-6-phosphate. The enzyme is assayed using a phosphatase-coupled kinase assay (4).
