| Comments |
This enzyme, along with EC?3.5.1.77?(N-carbamoyl-D-amino-acid hydrolase), EC?5.1.99.5?(hydantoin racemase) and hydantoinase, forms part of the reaction cascade known as the “hydantoinase process”, which allows the total conversion of?D,L-5-monosubstituted hydantoins into optically pure?D- or?L-amino acids [3]. The enzyme from?Alcaligenes xylosoxidans?has broad specificity for carbamoyl-L-amino acids, although it is inactive on the carbamoyl derivatives of glutamate, aspartate, arginine, tyrosine or tryptophan. The enzyme from?Sinorhizobium meliloti?requires a divalent cation for activity and can hydrolyse?N-carbamoyl-L-tryptophan as well as?N-carbamoyl?L-amino acids with aliphatic substituents [2]. The enzyme is inactive on derivatives of?D-amino acids. In addition to?N-carbamoyl?L-amino acids, the enzyme can also hydrolyse formyl and acetyl derivatives to varying degrees [1,2]. |
