Biol. 8:243-247(2001). CC -!- FUNCTION: Part of a heterotetrameric complex that catalyzes the CC two-step biosynthesis of anthranilate, an intermediate in the CC biosynthesis of L-tryptophan. In the first step, the glutamine- CC binding beta subunit (TrpG) of anthranilate synthase (AS) provides CC the glutamine amidotransferase activity which generates ammonia as CC a substrate that, along with chorismate, is used in the second CC step, catalyzed by the large alpha subunit of AS (TrpE) to produce CC anthranilate. In the absence of TrpG, TrpE can synthesize CC anthranilate directly from chorismate and high concentrations of CC ammonia. In addition to synthesizing anthranilate, it also CC catalyzes the second step of the pathway, the transfer of the CC phosphoribosyl group of 5-phosphorylribose-1-pyrophosphate (PRPP) CC to anthranilate. {ECO:0000269|PubMed:4914739}. CC -!- CATALYTIC ACTIVITY: CC Reaction=chorismate + L-glutamine = anthranilate + H(+) + L- CC glutamate + pyruvate; Xref=Rhea:RHEA:21732, ChEBI:CHEBI:15361, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16567, ChEBI:CHEBI:29748, CC ChEBI:CHEBI:29985, ChEBI:CHEBI:58359; EC=4.1.3.27; CC -!- CATALYTIC ACTIVITY: CC Reaction=diphosphate + N-(5-phospho-beta-D-ribosyl)anthranilate = CC 5-phospho-alpha-D-ribose 1-diphosphate + anthranilate; CC Xref=Rhea:RHEA:11768, ChEBI:CHEBI:16567, ChEBI:CHEBI:18277, CC ChEBI:CHEBI:33019, ChEBI:CHEBI:58017; EC=2.4.2.18; CC -!- ACTIVITY REGULATION: Cooperatively feedback inhibited by CC tryptophan. {ECO:0000269|PubMed:2022650, CC ECO:0000269|PubMed:4914739}. CC -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L- CC tryptophan from chorismate: step 1/5. CC -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L- CC tryptophan from chorismate: step 2/5. CC -!- SUBUNIT: Monomer. Heterotetramer consisting of two non-identical CC subunits: a beta subunit (TrpG) and a large alpha subunit (TrpE) CC (Probable). {ECO:0000305|PubMed:10089433, CC ECO:0000305|PubMed:11224570, ECO:0000305|PubMed:4914739}. CC -!- SIMILARITY: In the C-terminal section; belongs to the anthranilate CC phosphoribosyltransferase family. {ECO:0000305}.
