DE   2-succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylate synthase.
AN   2-succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylic acid synthase.
AN   6-hydroxy-2-succinylcyclohexa-2,4-diene-1-carboxylate synthase.
AN   SHCHC synthase.
CA   5-enolpyruvoyl-6-hydroxy-2-succinyl-cyclohex-3-ene-1-carboxylate =
CA   (1R,6R)-6-hydroxy-2-succinyl-cyclohexa-2,4-diene-1-carboxylate +
CA   pyruvate.
CC   -!- Involved in the biosynthesis of vitamin K2 (menaquinone).
CC   -!- In most anaerobes and all Gram-positive aerobes, menaquinone is the
CC       sole electron transporter in the respiratory chain and is essential
CC       for their survival.
CC   -!- It had previously been thought that the reactions carried out by this
CC       enzyme and EC 2.2.1.9 were carried out by a single enzyme but this
CC       has since been disproved.
CC   -!- Formerly EC 2.5.1.64 and EC 4.2.99.n1.
