Catalyzes the hydrolysis of N-carbamoyl-D-amino acids to the corresponding D-amino acids. Hydrolyzes aromatic and aliphatic N-carbamoyl-D-amino acids in vitro. Effectively hydrolyzes N-carbamoyl-D-p-hydroxyphenylglycine and N-carbamoyl-DL-p-hydroxyphenylglycine, and to a lesser extent N-carbamoyl-D-methionine. No activity for N-carbamoyl-L-amino acids, N-carbamoyl-beta-alanine or (RS)-alpha-ethyl-N-carbamoylphenylglycine in vitro. an N-carbamoyl-D-amino acid + 2 H(+) + H2O = a D-alpha-amino acid + CO2 + NH4(+) The activity decreases with increasing concentration of H(2)O(2). Has 68% and 43% of activity remaining upon treatment with 0.1 and 0.2 mM H(2)O(2) for 30 minutes, respectively. Inhibited significantly by 2 mM Zn(2+), Cu(2+) and Ag(+), moderately by Co(2+), Mn(2+), Sn(2+) and Mg(2+), and only slightly by Ba(2+). Slightly activated by Fe(2+) and Ca(2+). No effect on activity by metal chelators EDTA and 8-hydroxyquinoline at 2 mM or by dithiothreitol, 2-mercaptoethanol or phenylmethanesulfonyl fluoride. Optimum pH is 7.0. Stable at pH 6.5-8.2. Optimum temperature is 60 degrees Celsius. Very thermostable as still has 98% of its activity after incubation for 30 minutes at 50 degrees Celsius. Homotetramer. Has potential for industrial application in the enzymatic production of D-amino acids, which are very valuable intermediates for the production of semisynthetic antibiotics, peptide hormones, and pesticides.
