D-glutamate oxidase activity
Definition
Target type: molecularfunction
Catalysis of the reaction: D-glutamate + H2O + O2 = 2-oxoglutarate + NH3 + H2O2. [EC:1.4.3.7]
D-glutamate oxidase activity catalyzes the oxidative deamination of D-glutamate to α-ketoglutarate, ammonia, and hydrogen peroxide. This reaction involves the removal of an amino group from D-glutamate, with the simultaneous transfer of two electrons to molecular oxygen, which is reduced to hydrogen peroxide. The enzyme requires FAD as a cofactor, which is reduced to FADH2 during the reaction and then reoxidized by molecular oxygen. This activity is crucial for the catabolism of D-glutamate, a non-canonical amino acid, and plays a role in various biological processes, including amino acid metabolism, detoxification, and the production of reactive oxygen species. The enzyme is found in various organisms, including bacteria, fungi, and mammals, and its activity is regulated by factors such as pH, temperature, and the presence of inhibitors. Some D-glutamate oxidases exhibit broad substrate specificity, being able to oxidize other D-amino acids, while others are highly specific for D-glutamate.'
