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 {ECO:0000250}.
CC -!- SUBUNIT: Oligomer of 12 subunits arranged in the form of two
CC hexagons. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm.
CC -!- SIMILARITY: Belongs to the glutamine synthetase family.
CC {ECO:0000305}.
