IUBMB Enzyme Nomenclature

EC 2.7.3.8

Accepted name: ammonia kinase

Reaction: ATP + NH3 = ADP + phosphoramide

Other names: phosphoramidate-adenosine diphosphate phosphotransferase; phosphoramidate-ADP-phosphotransferase

Systematic name: ATP:ammonia phosphotransferase

Comments: Has a wide specificity. In the reverse direction, N-phosphoglycine and N-phosphohistidine can also act as phosphate donors, and ADP, dADP, GDP, CDP, dTDP, dCDP, IDP and UDP can act as phosphate acceptors (in decreasing order of activity).
