MANDELATE RACEMASE MUTANT K166R CO-CRYSTALLIZED WITH (R)-MANDELATE

Overview

On the basis of the available high-resolution structures of mandelate, racemase (MR) from Pseudomonas putida [Landro, J. A., Gerlt, J. A., Kozarich, J. W., Koo, C. W., Shah, V. J., Kenyon, G. L., Neidhart, D. J., Fujita, J., & Petsko, G. A. (1994) Biochemistry 33, 635-643], Lys 166 and, His 297 are positioned appropriately to participate in catalysis as, acid/base catalysts that either abstract the alpha-proton from the, enantiomers of mandelate to form an enolic intermediate or protonate the, enolic intermediate to form the enantiomers of mandelate, with Lys 166, participating as the (S)-specific acid/base catalyst and His 297, participating as the (R)-specific acid/base catalyst. In this paper we, report the structural and mechanistic properties of the mutant in which, Lys 166 has ... [(full description)]
