SYSTEMATIC NAME
IUBMB Comments
D-glutamate(D-aspartate):oxygen oxidoreductase (deaminating)
A flavoprotein (FAD). D-Glutamate and D-aspartate are oxidized at the same rate. Other D-monoaminodicarboxylates, and other D- and L-amino acids, are not oxidized. cf. EC 1.4.3.7, D-glutamate oxidase and EC 1.4.3.1, D-aspartate oxidase.
