AC MF_00300; DC Protein; auto TR HAMAP; MF_00300; -; 1; level=0 XX Names: Chorismate_synth XX ID AROC DE RecName: Full=Chorismate synthase; DE Short=CS; DE EC=4.2.3.5; DE AltName: Full=5-enolpyruvylshikimate-3-phosphate phospholyase; GN Name=aroC; XX 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. 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 -!- COFACTOR: CC Name=FMNH2; Xref=ChEBI:CHEBI:57618; CC Note=Reduced FMN (FMNH(2)).; CC -!- PATHWAY: Metabolic intermediate biosynthesis; chorismate biosynthesis; CC chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step CC 7/7. case CC -!- SUBUNIT: Homotetramer. end case CC -!- SIMILARITY: Belongs to the chorismate synthase family.
