In [[enzymology]], an '''allantoin racemase''' ({{EC number|5.1.99.3}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]<br />
<br />
:(S)(+)-allantoin <math>\rightleftharpoons</math> (R)(-)-allantoin<br />
<br />
Hence, this enzyme has one [[substrate (biochemistry)|substrate]], [[(S)(+)-allantoin]], and one [[product (chemistry)|product]], [[(R)(-)-allantoin]].<br />
<br />
This enzyme belongs to the family of [[isomerase]]s, specifically those [[racemase]]s and [[epimerase]]s acting on other compounds. The systematic name of this enzyme class is '''allantoin racemase'''. This enzyme participates in [[purine metabolism]]. <br />
