CC   -!- FUNCTION: Catalyzes a proton abstraction reaction that results in 2,5-
CC       elimination of pyruvate from 2-succinyl-5-enolpyruvyl-6-hydroxy-3-
CC       cyclohexene-1-carboxylate (SEPHCHC) and the formation of 2-succinyl-6-
CC       hydroxy-2,4-cyclohexadiene-1-carboxylate (SHCHC). {ECO:0000255|HAMAP-
CC       Rule:MF_01660}.
