H297N | H297N has no detectable mandelate racemase activity. However, H297N catalyzes the stereospecific elimination of Br- from racemic p-(bromomethyl)mandelate to give p-(methyl)benzoylformate in 45% yield at a rate equal to that measured for wild type enzyme | Pseudomonas putida |

(S)-mandelate = (R)-mandelate | reaction proceeds via a two-base mechanism in which Lys166 abstracts the alpha-proton from (S)-mandelate and His297 abstracts the alpha-proton from (R)-mandelate | Pseudomonas putida | |
(S)-mandelate = (R)-mandelate | the enzyme contains two distinct general acid/base catalysts: Lys166 which abstracts the alpha-proton from (S)-mandelate, and His297, which abstracts the alpha-proton from (R)-mandelate | Pseudomonas putida |
