Isochorismate then interacts with 2-oxoglutare and a hydrogen ion through a 2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylate synthase resulting in the release of a carbon dioxide and a 2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylate. The latter compound then interacts with (1R,6R)-2-succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylate synthase resulting in the release of a pyruvate and a (1R,6R)-6-hydroxy-2-succinylcyclohexa-2,4-diene-1-carboxylate. This compound is the dehydrated through a o-succinylbenzoate synthase resulting in the release of a water molecule and a 2-succinylbenzoate. This compound then interacts with a coenzyme A and an ATP through a o-succinylbenzoate CoA ligase resulting in the release of a diphosphate, a AMP and a succinylbenzoyl-CoA. The latter compound interacts with a hydrogen ion through a 1,4-dihydroxy-2-naphthoyl-CoA synthase resulting in the release of a water molecule or a 1,4-dihydroxy-2-naphthoyl-CoA. This compound then interacts with water through a 1,4-dihydroxy-2-naphthoyl-CoA thioesterase resulting in the release of a coenzyme A, a hydrogen ion and a 1,4-dihydroxy-2-naphthoate. The 1,4-dihydroxy-2-naphthoate can interact with either farnesylfarnesylgeranyl-PP or octaprenyl diphosphate and a hydrogen ion through a 1,4-dihydroxy-2-naphthoate octaprenyltransferase resulting in a release of a carbon dioxide, a pyrophosphate and a demethylmenaquinol-8. This compound then interacts with SAM through a bifunctional 2-octaprenyl-6-methoxy-1,4-benzoquinone methylase and S-adenosylmethionine:2-DMK methyltransferase resulting in a hydrogen ion, a s-adenosyl-L-homocysteine and a menaquinol.
