Protein attributes

Sequence length	471 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Catalytic activity	ATP + L-glutamate + NH3 = ADP + phosphate + L-glutamine.
Enzyme regulation	The activity of this enzyme is controlled by adenylation under conditions of abundant glutamine. The fully adenylated enzyme complex is inactive By similarity.
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the glutamine synthetase family.
