Protein

Anthranilate synthase component 2

Gene

trpG

Organism
Sulfolobus solfataricus (strain ATCC 35092 / DSM 1617 / JCM 11322 / P2)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Part of a heterotetrameric complex that catalyzes the two-step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilate directly from chorismate and high concentrations of ammonia Probable.1 Publication

Catalytic activityi

Chorismate + L-glutamine = anthranilate + pyruvate + L-glutamate.
