RT   (glnA) gene from Lactobacillus delbrueckii subsp. bulgaricus.";
RL   Appl. Environ. Microbiol. 58:3165-3169(1992).
CC   -!- CATALYTIC ACTIVITY: ATP + L-glutamate + NH(3) = ADP + phosphate +
CC       L-glutamine.
CC   -!- ENZYME REGULATION: Does not seem to be regulated by adenylation.
CC   -!- SUBUNIT: Oligomer of 12 subunits arranged in the form of two
CC       hexagons (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- SIMILARITY: Belongs to the glutamine synthetase family.
