| Abstract: | Hydantoinase catalyses the cleavage of the ring of DL-5-monosubstituted hydantoins, which is the key bioeatalyst involved in the production of chiral amino acids and is widely found in microbial world. The thermostability and substrate specificity of hydantoinase were briefly revieweol in the article, and the develapment trend was discassed. |
