N-acetylmuramic acid 6-phosphate etherase (EC 4.2.1.126, MurNAc-6-P etherase, MurQ) is an enzyme with systematic name (R)-lactate hydro-lyase (adding N-acetyl-D-glucosamine 6-phosphate; N-acetylmuramate 6-phosphate-forming).[1][2][3][4][5] This enzyme catalyses the following chemical reaction
- (R)-lactate + N-acetyl-D-glucosamine 6-phosphate [math]\displaystyle{ \rightleftharpoons }[/math] N-acetylmuramate 6-phosphate + H2O
This enzyme is required for the utilization of anhydro-N-acetylmuramic acid in some Pseudomonadota.
