FAD dependent oxidoreductase family
In molecular biology, the FAD dependent oxidoreductase family of proteins is a family of FAD dependent oxidoreductases. Members of this family include Glycerol-3-phosphate dehydrogenase EC 1.1.99.5, Sarcosine oxidase beta subunit EC 1.5.3.1, D-amino-acid dehydrogenase EC 1.4.99.1, D-aspartate oxidase EC 1.4.3.1.

D-amino acid oxidase EC 1.4.3.3 (DAMOX or DAO) is an FAD flavoenzyme that catalyses the oxidation of neutral and basic D-amino acids into their corresponding keto acids. DAOs have been characterised and sequenced in fungi and vertebrates where they are known to be located in the peroxisomes.
D-aspartate oxidase EC 1.4.3.1 (DASOX) [1] is an enzyme, structurally related to DAO, which catalyses the same reaction but is active only toward dicarboxylic D-amino acids. In DAO, a conserved histidine has been shown [2] to be important for the enzyme's catalytic activity.
