CC   -!- CATALYTIC ACTIVITY: ATP + L-glutamate + NH(3) = ADP + phosphate +
CC       L-glutamine.
CC   -!- ENZYME REGULATION: The activity of this enzyme is controlled by
CC       adenylation under conditions of abundant glutamine. The fully
CC       adenylated enzyme complex is inactive (By similarity).
CC   -!- SUBUNIT: Oligomer of 12 subunits arranged in the form of two
CC       hexagons (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- SIMILARITY: Belongs to the glutamine synthetase family.
