[[http://www.uniprot.org/uniprot/MENH_ECOLI MENH_ECOLI]] 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). Is also able to catalyze the hydrolysis of the thioester bond in palmitoyl-CoA in vitro.<ref>PMID:15808744</ref> <ref>PMID:18284213</ref>
