摘要：
The present invention provides a novel ascorbate oxidase (ASOD) which catalyzes oxidation reaction of L-ascorbic acid with molecular oxygen to form L-dehydroascorbic acid and hydrogen peroxide, a process for producing the ascorbate oxidase comprising using a microorganism belonging to the genus Eupenicillium, a gene encoding ASOD, a transformant containing such a gene, a process for producing ASOD using such a transformant, and a reagent composition comprising ASOD, such as a reagent composition for examination, a food additive, and a reagent composition in the fields of food and clinical examination. The ascorbate oxidase has excellent stability particularly in a liquid state.
