CC Evidence={ECO:0000250|UniProtKB:P0A1P6};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:P9WN39};
CC Note=Binds 2 Mg(2+) ions per subunit. {ECO:0000250|UniProtKB:P9WN39};
CC -!- ACTIVITY REGULATION: The activity of this enzyme could be controlled by
CC adenylation under conditions of abundant glutamine.
CC {ECO:0000250|UniProtKB:Q3V5W6}.
CC -!- SUBUNIT: Oligomer of 12 subunits arranged in the form of two hexameric
CC ring. {ECO:0000250|UniProtKB:P0A1P6}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P9WN39}.
CC -!- SIMILARITY: Belongs to the glutamine synthetase family. {ECO:0000305}.
