racemase

 [ra´sĕ-mās]
an enzyme that catalyzes the racemization of an optically active substance, such as l-lactic acid.

ra·ce·mase

(rā'sē-māz),
An enzyme capable of catalyzing racemization, that is, inversions of asymmetric groups; when more than one center of asymmetry is present, "epimerase" is used (for example, hydroxyproline, methylmalonyl-CoA).

racemase

/ra·ce·mase/ (ra´sĕ-mās) an enzyme that catalyzes inversion around the asymmetric carbon atom in a substrate having only one center of asymmetry.
