Enzyme Information

3.5.1.77
N-carbamoyl-D-amino-acid hydrolase.
based on mapping to UniProt Q44185
N-carbamoyl-D-amino acid + H(2)O = D-amino acid + NH(3) + CO(2).
-!- This enzyme, along with EC 3.5.1.87, EC 5.1.99.5 and EC 3.5.2.2, 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. -!- Has strict stereospecificity for N-carbamoyl-D-amino acids and does not act upon the corresponding L-amino acids or N-formyl amino acids, N-carbamoyl-sarcosine, -citrulline, -allantoin and -ureidopropanoate, which are substrates for other amidohydrolases.
