CC   -!- FUNCTION: Catalyzes the thiamine diphosphate-dependent decarboxylation
CC       of 2-oxoglutarate and the subsequent addition of the resulting succinic
CC       semialdehyde-thiamine pyrophosphate anion to isochorismate to yield 2-
CC       succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylate (SEPHCHC).
CC       {ECO:0000255|HAMAP-Rule:MF_01659}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-oxoglutarate + H(+) + isochorismate = 5-enolpyruvoyl-6-
CC         hydroxy-2-succinyl-cyclohex-3-ene-1-carboxylate + CO2;
