FunctionMandelate rasemase (MAR) catalyzes the interconversion of enantiomers of mandelate (S to R). MAR is Mg-dependent. MAR can racemize other alpha-hydroxy carbonyl compounds. MAR is involved in aromatic acids catabolism[1]. Structural highlightsThe biological assembly of mandelate racemase from Pseudomonas putida is . The [2]. Water molecule shown as red sphere. |
