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 (By similarity).
CC       {ECO:0000250}.
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   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000250|UniProtKB:P00897};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000250|UniProtKB:P00897};
CC   -!- ACTIVITY REGULATION: Feedback inhibited by tryptophan. {ECO:0000250}.
CC   -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L-
CC       tryptophan from chorismate: step 1/5.
CC   -!- SUBUNIT: Heterotetramer consisting of two non-identical subunits: a
CC       beta subunit (TrpG) and a large alpha subunit (TrpE). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the anthranilate synthase component I family.
CC       {ECO:0000305}.
