KEGG   ENZYME: 2.7.3.8Help
Entry
EC 2.7.3.8                  Enzyme                                 

Name
ammonia kinase;
phosphoramidate-adenosine diphosphate phosphotransferase;
phosphoramidate-ADP-phosphotransferase
Class
Transferases;
Transferring phosphorus-containing groups;
Phosphotransferases with a nitrogenous group as acceptor
BRITE hierarchy
Sysname
ATP:ammonia phosphotransferase
Reaction(IUBMB)
ATP + NH3 = ADP + phosphoramide [RN:R00141]
Reaction(KEGG)
Substrate
ATP [CPD:C00002];
NH3 [CPD:C00014]
Product
ADP [CPD:C00008];
phosphoramide [CPD:C02058]
Comment
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).
