Anhydro-N-acetylmuramic acid kinase
Anhydro-N-acetylmuramic acid kinase (EC 2.7.1.170, anhMurNAc kinase, AnmK) is an enzyme with systematic name ATP:1,6-anhydro-N-acetyl-beta-muramate 6-phosphotransferase.[1][2][3] This enzyme catalyses the following chemical reaction
- ATP + 1,6-anhydro-N-acetyl-beta-muramate + H2O ADP + N-acetylmuramate 6-phosphate
