Abstract: D-amino acid oxidase catalyzes oxidative deamination of D-amino acids yielding α-keto acid and ammonia, the reduced flavin is reoxidized to generate hydrogen peroxide by molecular oxygen. D-amino acid oxidase plays a key role in the pathophysiology of schizophrenia research and D-amino acids detecting. Based on the three-dimensional structure of analyzed D-amino acid oxidases, the property of the enzyme could be improved by rational protein design. In order to get a better understanding of D-amino acid oxidase, the sequence homology, overall structure, the active site center, inhibitor, FAD binding site and flexible parts of DAAO were introduced.

Key words: D-amino acid oxidase, Overall structure, Active site, Inhibitor, FAD
