ENTRY       EC 2.7.3.8
NAME        Ammonia kinase
CLASS       Transferases
            Transferring phosphorus-containing groups
            Phosphotransferases with a nitrogenous group as acceptor
SYSNAME     ATP:ammonia phosphotransferase
REACTION    ATP + NH3 = ADP + Phosphoramide
SUBSTRATE   ATP
            NH3
PRODUCT     ADP
            Phosphoramide
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).
