CC   -!- CATALYTIC ACTIVITY: ATP + L-glutamate + NH(3) = ADP + phosphate +
CC       L-glutamine.
CC   -!- SUBUNIT: Homooctamer.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- MISCELLANEOUS: In pea there are distinct isozymes in leaves, roots
CC       and nodules.
CC   -!- MISCELLANEOUS: Irreversibly inhibited by the herbicide L-
CC       phosphinothricin (PPT).
CC   -!- SIMILARITY: Belongs to the glutamine synthetase family.
