MurQ etherase is required by Escherichia coli in order to metabolize anhydro-N-acetylmuramic acid obtained either from the environment or from its own cell wall.
Uehara T., Suefuji K., Jaeger T., Mayer C., Park J.T.
MurQ is an N-acetylmuramic acid-phosphate (MurNAc-P) etherase that converts MurNAc-P to N-acetylglucosamine-phosphate and is essential for growth on MurNAc as the sole source of carbon (T. Jaegar, M. Arsic, and C. Mayer, J. Biol. Chem. 280:30100-30106, 2005). Here we show that MurQ is the only Mur ... >> More
MurQ is an N-acetylmuramic acid-phosphate (MurNAc-P) etherase that converts MurNAc-P to N-acetylglucosamine-phosphate and is essential for growth on MurNAc as the sole source of carbon (T. Jaegar, M. Arsic, and C. Mayer, J. Biol. Chem. 280:30100-30106, 2005). Here we show that MurQ is the only MurNAc-P etherase in Escherichia coli and that MurQ and AnmK kinase are required for utilization of anhydro-MurNAc derived either from cell wall murein or imported from the medium. << Less

Recycling of the anhydro-N-acetylmuramic acid derived from cell wall murein involves a two-step conversion to N-acetylglucosamine-phosphate.
Uehara T., Suefuji K., Valbuena N., Meehan B., Donegan M., Park J.T.
Escherichia coli breaks down over 60% of the murein of its side wall and reuses the component amino acids to synthesize about 25% of the cell wall for the next generation. The amino sugars of the murein are also efficiently recycled. Here we show that the 1,6-anhydro-N-acetylmuramic acid (anhMurNA ... >> More
Escherichia coli breaks down over 60% of the murein of its side wall and reuses the component amino acids to synthesize about 25% of the cell wall for the next generation. The amino sugars of the murein are also efficiently recycled. Here we show that the 1,6-anhydro-N-acetylmuramic acid (anhMurNAc) is returned to the biosynthetic pathway by conversion to N-acetylglucosamine-phosphate (GlcNAc-P). The sugar is first phosphorylated by anhydro-N-acetylmuramic acid kinase (AnmK), yielding MurNAc-P, and this is followed by action of an etherase which cleaves the bond between D-lactic acid and the N-acetylglucosamine moiety of MurNAc-P, yielding GlcNAc-P. The kinase gene has been identified by a reverse genetics method. The enzyme was overexpressed, purified, and characterized. The cell extract of an anmK deletion mutant totally lacked activity on anhMurNAc. Surprisingly, in the anmK mutant, anhMurNAc did not accumulate in the cytoplasm but instead was found in the medium, indicating that there was rapid efflux of free anhMurNAc. << Less
