additional information | substrate recognition and binding method, overview. Mandelate racemase from Pseudomonas putida catalyzes the interconversion of the enantiomers of mandelic acid and a variety of aryl- and heteroaryl-substituted mandelate derivatives. beta,gamma-Unsaturation is not an absolute requirement for catalysis and that mandelate racemase can bind and catalyze the racemization of (S)- and (R)-trifluorolactate. The enzyme catalyzes hydrogen-deuterium exchange at the alpha-postion of trifluorolactate | Pseudomonas putida | ? | - |
