N-carbamoyl-L-amino-acid hydrolase
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. 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. The enzymeis 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. Group: Enzymes. Synonyms: N-carbamyl L-amino acid amidohydrolase; N-carbamoyl-L-amino acid amidohydrolase; L-N-car. Enzyme Commission Number: EC 3.5.1.87. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-4478; N-carbamoyl-L-amino-acid hydrolase; EC 3.5.1.87; N-carbamyl L-amino acid amidohydrolase; N-carbamoyl-L-amino acid amidohydrolase; L-N-carbamoylase; N-carbamoylase (ambiguous). Cat No: EXWM-4478.
