摘要 D-amino acid oxidase (DAO) is a peroxisomal enzyme that catalyzes the oxidative deamination of D-amino acids. In this study, we employed a bacterial expression system to express and purify a ~38 kDa recombinant zebrafish DAO (zDAO) protein. The kinetic parameters, including Km (μM), Kcat (nmol/min/mg), and substrate specificity (Kcat/Km), were determined. All D-amino acids were tested as substrates. Among them, zDAO exhibited the highest specificity for D-alanine (0.537), making it the preferred substrate. In contrast, D-threonine showed the lowest specificity (0.018), approximately 3% of that for D-alanine. These findings provide further insight into the enzymatic properties of fish DAO.
