title: Determination of the stereochemistry of 2-succinyl-5-enolpyruvyl-6-hydroxy-3- cyclohexene-1-carboxylate, a key intermediate in menaquinone biosynthesis.
abstract: The turnover product of the committed step of menaquinone biosynthesis was isolated and determined to be (1R,2S,5S,6S)-2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylate. Structural determination of this key intermediate represents a critical step to complete elucidation of the biosynthetic pathway.
