EC Number: 188.8.131.52
In Pathway: anhydromuropeptides recycling
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
Mass balance status: Balanced.
Enzyme Commission Primary Name: N-acetylmuramic acid 6-phosphate etherase
Enzyme Commission Synonyms: MurNAc-6-P etherase, MurQ
Enzyme Commission Summary:
This enzyme, along with EC 184.108.40.206, anhydro-N-acetylmuramic acid kinase, is required for the utilization of anhydro-N-acetylmuramic acid in proteobacteria. The substrate is either imported from the medium or derived from the bacterium's own cell wall murein during cell wall recycling.
