FUNCTION | Catalyzes a proton abstraction reaction that results in 2,5- elimination of pyruvate from 2-succinyl-5-enolpyruvyl-6-hydroxy-3- cyclohexene-1-carboxylate (SEPHCHC) and the formation of 2-succinyl-6- hydroxy-2,4-cyclohexadiene-1-carboxylate (SHCHC). |
CATALYTIC ACTIVITY | Reaction=5-enolpyruvoyl-6-hydroxy-2-succinyl-cyclohex-3-ene-1- carboxylate = (1R,6R)-6-hydroxy-2-succinyl-cyclohexa-2,4-diene-1- carboxylate + pyruvate; Xref=Rhea:RHEA:25597, ChEBI:CHEBI:15361, ChEBI:CHEBI:58689, ChEBI:CHEBI:58818; EC=4.2.99.20; |
PATHWAY | Quinol/quinone metabolism; 1,4-dihydroxy-2-naphthoate biosynthesis; 1,4-dihydroxy-2-naphthoate from chorismate: step 3/7. |
