Anhydro-N-acetylmuramic acid kinase ({{EC number|2.7.1.170}}, anhMurNAc kinase, AnmK) is an enzyme with systematic name ATP:1,6-anhydro-N-acetyl-beta-muramate 6-phosphotransferase.{{cite journal | vauthors = Uehara T, Suefuji K, Valbuena N, Meehan B, Donegan M, Park JT | title = Recycling of the anhydro-N-acetylmuramic acid derived from cell wall murein involves a two-step conversion to N-acetylglucosamine-phosphate | journal = Journal of Bacteriology | volume = 187 | issue = 11 | pages = 3643–9 | date = June 2005 | pmid = 15901686 | pmc = 1112033 | doi = 10.1128/jb.187.11.3643-3649.2005 }}{{cite journal | vauthors = Uehara T, Suefuji K, Jaeger T, Mayer C, Park JT | title = 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 | journal = Journal of Bacteriology | volume = 188 | issue = 4 | pages = 1660–2 | date = February 2006 | pmid = 16452451 | pmc = 1367226 | doi = 10.1128/jb.188.4.1660-1662.2006 }}{{cite journal | vauthors = Bacik JP, Whitworth GE, Stubbs KA, Yadav AK, Martin DR, Bailey-Elkin BA, Vocadlo DJ, Mark BL | title = Molecular basis of 1,6-anhydro bond cleavage and phosphoryl transfer by Pseudomonas aeruginosa 1,6-anhydro-N-acetylmuramic acid kinase | journal = The Journal of Biological Chemistry | volume = 286 | issue = 14 | pages = 12283–91 | date = April 2011 | pmid = 21288904 | pmc = 3069431 | doi = 10.1074/jbc.m110.198317 | doi-access = free }} This enzyme catalyses the following chemical reaction

: ATP + 1,6-anhydro-N-acetyl-beta-muramate + H₂O $\backslash rightleftharpoons$ ADP + N-acetylmuramate 6-phosphate

This enzyme is required for the use of anhydro-N-acetylmuramic acid in Pseudomonadota.
