Chains	Enzyme Name	Description	Catalytic Residues
A	mandelate racemase M-CSA #187	Mandelate racemase enzymes catalyse the interconversion of the (R)- and (S)-enantiomers of mandelate, in the pathway for catabolism of mandelate. This pathway, that synthesises benzoate from, (R)-mandelate, is quite specialised, and, to date, only been identified in a small number of bacteria, including Pseudomonas putida.
