Known as: negative regulation of D-amino-acid:oxygen oxidoreductase (deaminating), down-regulation of D-amino-acid:oxygen oxidoreductase (deaminating), downregulation of L-amino acid:O2 oxidoreductase activity
Any process that stops, prevents or reduces the frequency, rate or extent of D-amino-acid oxidase activity. [GOC:TermGenie]
