Predicted to enable D-aspartate oxidase activity and FAD binding activity. Predicted to be involved in D-amino acid catabolic process and aspartate catabolic process. Predicted to act upstream of or within several processes, including aspartate metabolic process; grooming behavior; and insemination. Predicted to be located in cytosol. Predicted to be active in cytoplasm. Orthologous to human DDO (D-aspartate oxidase). [provided by Alliance of Genome Resources, Apr 2022]
