Menaquinone biosynthesis is initiated by the conversion of chorismate to isochorismate, a reaction that is catalyzed by the menaquinone-specific isochorismate synthase, MenF. The catalytic mechanism of MenF has been probed using a combination of structural and biochemical studies, including the 2.5 A structure of the enzyme, and Lys190 has been identified as the base that activates water for nucleophilic attack at the chorismate C2 carbon. MenF is a member of a larger family of Mg2+ dependent chorismate binding enzymes catalyzing distinct chorismate transformations. The studies reported here extend the mechanism recently proposed for this enzyme family by He et al.: He, Z., Stigers Lavoie, K. D., Bartlett, P. A., and Toney, M. D. (2004) J. Am. Chem. Soc. 126, 2378-85.
