Sysname
N-carbamoyl-D-amino-acid amidohydrolase
Reaction(IUBMB)
an N-carbamoyl-D-amino acid + H2O = a D-amino acid + NH3 + CO2 [RN:R02190]
Reaction(KEGG)
Substrate
N-carbamoyl-D-amino acid [CPD:C05226];
H2O [CPD:C00001]
Product

Comment
This enzyme, along with EC 3.5.1.87 (N-carbamoyl-L-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 [2]. It has strict stereospecificity for N-carbamoyl-D-amino acids and does not act upon the corresponding L-amino acids or on the N-formyl amino acids, N-carbamoyl-sarcosine, -citrulline, -allantoin and -ureidopropanoate, which are substrates for other amidohydrolases.
