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}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-enolpyruvoyl-6-hydroxy-2-succinyl-cyclohex-3-ene-1-
CC carboxylate = (1R,6R)-6-hydroxy-2-succinyl-cyclohexa-2,4-diene-1-
CC carboxylate + pyruvate; Xref=Rhea:RHEA:25597, ChEBI:CHEBI:15361,
CC ChEBI:CHEBI:58689, ChEBI:CHEBI:58818; EC=4.2.99.20;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01660};
CC -!- PATHWAY: Quinol/quinone metabolism; 1,4-dihydroxy-2-naphthoate
CC biosynthesis; 1,4-dihydroxy-2-naphthoate from chorismate: step 3/7.
CC {ECO:0000255|HAMAP-Rule:MF_01660}.
CC -!- PATHWAY: Quinol/quinone metabolism; menaquinone biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_01660}.
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01660}.
CC -!- SIMILARITY: Belongs to the AB hydrolase superfamily. MenH family.
CC {ECO:0000255|HAMAP-Rule:MF_01660}.
