Accepted name: glutamate—ammonia ligase
Reaction: ATP + L-glutamate + NH3 = ADP + phosphate + L-glutamine
Other name(s): glutamine synthetase; glutamylhydroxamic synthetase; L-glutamine synthetase
Systematic name: L-glutamate:ammonia ligase (ADP-forming)
Comments: Also acts, more slowly, on 4-methylene-L-glutamate (cf. EC 4-methyleneglutamate—ammonia ligase).
