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:0000255|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:0000255|HAMAP-Rule:MF_00300};
CC   -!- COFACTOR:
CC       Name=FMNH2; Xref=ChEBI:CHEBI:57618; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00300};
CC       Note=Reduced FMN (FMNH(2)). {ECO:0000255|HAMAP-Rule:MF_00300};
CC   -!- PATHWAY: Metabolic intermediate biosynthesis; chorismate biosynthesis;
CC       chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step
CC       7/7. {ECO:0000255|HAMAP-Rule:MF_00300}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00300}.
CC   -!- SIMILARITY: Belongs to the chorismate synthase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00300}.
