a D-amino acid + H2O + a quinone = a 2-oxo carboxylate + NH3 + a quinol
D-amino acid:quinone oxidoreductase (deaminating)
An iron-sulfur flavoprotein (FAD). The enzyme from the bacterium Helicobacter pylori is highly specific for D-proline, while the enzyme from the bacterium Escherichia coli B is most active with D-alanine, D-phenylalanine and D-methionine. This enzyme may be the same as EC 188.8.131.52.
