Glutamine synthetase.
based on mapping to UniProt P9WN39
ATP + L-glutamate + NH(3) = ADP + phosphate + L-glutamine.
-!- Glutamine synthetase, which catalyzes the incorporation of ammonium into glutamate, is a key enzyme of nitrogen metabolism found in all domains of life. -!- Several types have been described, differing in their oligomeric structures and cofactor requirements.
