Protein attributes

Sequence length	191 AA.
Sequence status	Complete.
Protein existence	Predicted

General annotation (Comments)

Function	Catalyzes the biosynthesis of 4-amino-4-deoxychorismate (ADC) from chorismate and glutamine.
Catalytic activity	Chorismate + L-glutamine = 4-amino-4-deoxychorismate + L-glutamate.
Pathway	Cofactor biosynthesis; tetrahydrofolate biosynthesis; 4-aminobenzoate from chorismate: step 1/2.
Subunit structure	Consists of two non-identical chains: component I catalyzes the formation of ADC by binding chorismate and ammonia; component II provides the glutamine amidotransferase activity.
Sequence similarities	Contains 1 glutamine amidotransferase type-1 domain.
