ABSTRACT:
The present invention provides a novel fructosyl amino acid oxidase that is excellent in thermal stability. Moreover, the present invention provides a fructosyl amino acid oxidase gene encoding the novel fructosyl amino acid oxidase, a recombinant DNA in which the gene is inserted into a vector DNA, a transformant or transductant containing this gene, and a process for producing the novel fructosyl amino acid oxidase, which comprises culturing the transformant or transductant in a medium and collecting the novel fructosyl amino acid oxidase from the culture product.
