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