Abstract

The substrate specificity of duckling hepatic and renal D-amino acid oxidase (DAAO; D-amino acid: O2 oxidoreductase [deaminating], E.C. 1.4.3.3) was determined using a method based on the combination of coupled enzyme reactions and a colorimetric procedure. When activities were averaged across tissues, D-proline was the most reactive substrate, followed by (in order) D-phenylalanine, D-alanine, D-methionine, D-leucine, D-isoleucine, D-valine, D-tryptophan, D-arginine, and D-lysine. Compared with D-alanine, duckling DAAO had minimal or no reactivity with D-asparagine, D-glutamine, D-histidine, D-threonine, D-cysteine, glycine, or D-serine. These results were in general agreement with data from other vertebrate species.
