Epimerase and racemase

Epimerases and racemases are isomerase enzymes that catalyze the inversion of stereochemistry in biological molecules.[1] Racemases catalyze the stereochemical inversion around the asymmetric carbon atom in a substrate having only one center of asymmetry. Epimerases catalyze the stereochemical inversion of the configuration about an asymmetric carbon atom in a substrate having more than one center of asymmetry; thus interconverting epimers.
