IUBMB Enzyme Nomenclature


Accepted name: L-glutamate oxidase

Reaction: L-glutamate + O2 + H2O = 2-oxoglutarate + NH3 + H2O2

Other name(s): glutamate (acceptor) dehydrogenase; glutamate oxidase; glutamic acid oxidase; glutamic dehydrogenase (acceptor); L-glutamic acid oxidase

Systematic name: L-glutamate:oxygen oxidoreductase (deaminating)

Comments: A flavoprotein (FAD). The enzyme from Azotobacter previously listed under this number, which did not produce H2O2, was a crude cell-free extract that probably contained catalase.
