Protein
PTS system N-acetylglucosamine-specific EIICBA component
Gene
nagE
Organism
Escherichia coli (strain K12)
Status
Functioni
The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane (PubMed:4919472). This system is involved in N-acetylglucosamine transport (PubMed:4919472). It can also transport and phosphorylate the antibiotic streptozotocin (PubMed:161156). Could play a significant role in the recycling of peptidoglycan (PubMed:19617367).1 Publication3 Publications

Activity regulationi
P-chloromercuribenzoate inhibits the accumulation of both N-acetyl-D-glucosamine and antibiotic streptozotocin (2-deoxy-2-(3-methyl-3-nitrosoureido)-D-glucopyranose). N-acetyl-D-glucosamine is a competitive inhibitor for the uptake of streptozotocin.1 Publication

Disruption phenotypei
Cells lacking nagE and nagA reduce by 50% the amount of GlcNAc6P. Together with the mutations of the genes of the peptidoglycan recycling pathway (ampG, anmK, murQ, nagK and nagZ), the accumulation of GlcNAc6P is eliminated.1 Publication

Domaini
The PTS EIIC type-1 domain forms the PTS system translocation channel and contains the specific substrate-binding site.PROSITE-ProRule annotation
The PTS EIIB type-1 domain is phosphorylated by phospho-EIIA on a cysteinyl residue. Then, it transfers the phosphoryl group to the sugar substrate concomitantly with the sugar uptake processed by the PTS EIIC type-1 domain.PROSITE-ProRule annotation
The PTS EIIA type-1 domain is phosphorylated by phospho-HPr on a histidyl residue. Then, it transfers the phosphoryl group to the PTS EIIB type-1 domain.PROSITE-ProRule annotation
