A	o-succinylbenzoate synthase M-CSA #689	o-Succinylbenzoate synthase (OSBS) is a member of the muconate lactonising enzyme subgroup of the enolase superfamily. It catalyses the exergonic dehydration reaction in the menaquinone biosynthesis pathway in which 2-succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylate (SHCHC) is converted to o-succinylbenzoate.
