In enzymology, a N-carbamoyl-D-amino acid hydrolase () is an enzyme that catalyzes the chemical reaction N-carbamoyl-D-amino acid + H2O D-amino acid + NH3 + CO2 Thus, the two substrates of this enzyme are N-carbamoyl-D-amino acid and H2O, whereas its 3 products are D-amino acid, NH3, and CO2. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. Structural studies As of late 2007, 7 structures have been solved for this class of enzymes, with PDB accession codes , , , , , , and . References EC 3.5.1 Enzymes of known structure
