- Diphthine-ammonia ligase
In
enzymology , a diphthine-ammonia ligase (EC number|6.3.2.22) is anenzyme that catalyzes thechemical reaction :ATP + diphthine + NH3 ightleftharpoons ADP + phosphate + diphthamide
The 3 substrates of this enzyme are ATP,
diphthine , and NH3, whereas its 3 products are ADP,phosphate , anddiphthamide .This enzyme belongs to the family of
ligase s, specifically those forming carbon-nitrogen bonds as acid-D-amino-acid ligases (peptide synthases). The systematic name of this enzyme class is diphthine:ammonia ligase (ADP-forming). Other names in common use include diphthamide synthase, and diphthamide synthetase.References
