CC -!- FUNCTION: Catalyzes the Claisen rearrangement of chorismate to
CC prephenate and the decarboxylation/dehydration of prephenate to
CC phenylpyruvate. {ECO:0000256|ARBA:ARBA00002364}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + prephenate = 3-phenylpyruvate + CO2 + H2O;

CC ChEBI:CHEBI:16526, ChEBI:CHEBI:18005, ChEBI:CHEBI:29934; EC=4.2.1.51;
CC Evidence={ECO:0000256|ARBA:ARBA00000913};
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:0000256|ARBA:ARBA00000824};
CC -!- PATHWAY: Amino-acid biosynthesis; L-phenylalanine biosynthesis;
CC phenylpyruvate from prephenate: step 1/1.
CC {ECO:0000256|ARBA:ARBA00004741}.
CC -!- PATHWAY: Metabolic intermediate biosynthesis; prephenate biosynthesis;
CC prephenate from chorismate: step 1/1. {ECO:0000256|ARBA:ARBA00004817}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
