ID   2.7.3.8
DE   ammonia kinase.
CA   NH4(+) + ATP = phosphoramidate + ADP + 2 H(+).
CC   -!- Has a wide specificity.
CC   -!- In the reverse direction, N-phosphoglycine and N-phosphohistidine can
CC       also act as phosphate donors, and ADP, dADP, GDP, CDP, dTDP, dCDP,
CC       IDP and UDP can act as phosphate acceptors (in decreasing order of
CC       activity).
