Comments [?]

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 RHEA:25597: 5-enolpyruvoyl-6-hydroxy-2-succinyl-cyclohex-3-ene-1-carboxylate = (1R,6R)-6-hydroxy-2-succinyl-cyclohexa-2,4-diene-1-carboxylate + pyruvate
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.
case not <OC:Cyanobacteriota>
Pathway Quinol/quinone metabolism; menaquinone biosynthesis.
else case <OC:Cyanobacteriota>
Pathway Cofactor biosynthesis; phylloquinone biosynthesis.
end case
Subunit Monomer.
Similarity Belongs to the AB hydrolase superfamily. MenH family.
