CC   -!- FUNCTION: Catalyzes the Claisen rearrangement of chorismate to
CC       prephenate (By similarity). Acts at the first branch point in the
CC       aromatic amino acid pathway where it steers biosynthesis towards
CC       phenylalanine and tyrosine, and away from tryptophan (By similarity).
CC       {ECO:0000250|UniProtKB:P32178}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=chorismate = prephenate; Xref=Rhea:RHEA:13897,
CC         ChEBI:CHEBI:29748, ChEBI:CHEBI:29934; EC=5.4.99.5;

CC         Evidence={ECO:0000250|UniProtKB:P32178};
CC   -!- ACTIVITY REGULATION: Each dimer has two allosteric binding sites that
CC       can bind the regulatory effectors tryptophan or tyrosine (By
CC       similarity). Can bind either one tryptophan or one tyrosine, two
CC       tryptophan or two tyrosine or one tryptophan and one tyrosine, which
CC       differentially affect the catalytic activity (By similarity). Activated
CC       by tryptophan and subject to feedback inhibition by tyrosine (By
CC       similarity). In the presence of both tryptophan and tyrosine, the
CC       enzyme is in the activated state (By similarity).
CC       {ECO:0000250|UniProtKB:P32178}.
CC   -!- PATHWAY: Metabolic intermediate biosynthesis; prephenate biosynthesis;
CC       prephenate from chorismate: step 1/1. {ECO:0000250|UniProtKB:P32178}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P32178}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P32178}.
