There is provided a dried L-glutamate oxidase composition containing an L-glutamate oxidase, which is stable even if it is stored for such a long term as one year or longer. The composition is a dried composition, preferably lyophilized product, containing an L-glutamate oxidase and a disaccharide. A preferred example of the disaccharide is lactose. Content of the disaccharide per 100 U of the L-glutamate oxidase is preferably 0.5 to 50 mg.

Dried L-glutamate oxidase composition

The present invention provides a novel L-glutamate oxidase, a gene encoding the enzyme, and a method for producing the enzyme. By use of a gene encoding the enzyme, L-glutamate oxidase can be readily prepared at low costs through a recombinant DNA technique. The novel L-glutamate oxidase has the following physicochemical properties:
