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:0000256|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;
