Protein attributes

Sequence length	194 AA.
Sequence status	Complete.
Protein existence	Predicted

General annotation (Comments)

Catalytic activity	Chorismate + L-glutamine = anthranilate + pyruvate + L-glutamate.
Pathway	Amino-acid biosynthesis; L-tryptophan biosynthesis; L-tryptophan from chorismate: step 1/5.
Subunit structure	Tetramer of two components I and two components II.
Miscellaneous	Component I catalyzes the formation of anthranilate using ammonia rather than glutamine, whereas component II provides glutamine amidotransferase activity.
Sequence similarities	Contains 1 glutamine amidotransferase type-1 domain.
