CC -!- FUNCTION: Catalyzes the anti-1,4-elimination of the C-3 phosphate and
CC the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to
CC yield chorismate, which is the branch point compound that serves as the
CC starting substrate for the three terminal pathways of aromatic amino
CC acid biosynthesis. This reaction introduces a second double bond into
CC the aromatic ring system. {ECO:0000256|HAMAP-Rule:MF_00300}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-O-(1-carboxyvinyl)-3-phosphoshikimate = chorismate +
CC phosphate; Xref=Rhea:RHEA:21020, ChEBI:CHEBI:29748,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:57701; EC=4.2.3.5;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00300,
CC ECO:0000256|RuleBase:RU000605};
CC -!- COFACTOR:
CC Name=FMNH2; Xref=ChEBI:CHEBI:57618;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00300,
CC ECO:0000256|RuleBase:RU000605};
CC Note=Reduced FMN (FMNH(2)). {ECO:0000256|HAMAP-Rule:MF_00300,
CC ECO:0000256|RuleBase:RU000605};
CC -!- PATHWAY: Metabolic intermediate biosynthesis; chorismate biosynthesis;
CC chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step
CC 7/7. {ECO:0000256|ARBA:ARBA00005044, ECO:0000256|HAMAP-Rule:MF_00300,
CC ECO:0000256|RuleBase:RU000605}.
CC -!- SIMILARITY: Belongs to the chorismate synthase family.
CC {ECO:0000256|ARBA:ARBA00008014, ECO:0000256|HAMAP-Rule:MF_00300,
CC ECO:0000256|RuleBase:RU000605}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00300}.
