Hydantoin racemase (EC 5.1.99.5, 5'-monosubstituted-hydantoin racemase, HyuA, HyuE) is an enzyme with system name D-5-monosubstituted-hydantoin racemase.[1][2][3][4][5][6][7] This enzyme catalyses the following chemical reaction

D-5-monosubstituted hydantoin \rightleftharpoons L-5-monosubstituted hydantoin

This enzyme is a part of the reaction cascade known as the "hydantoinase process".
