(57) Abstract: The present invention provides a gene for levanfructotransferase, a recombinant DNA containing the gene, a transformant having the recombinant DNA, and a levanfructotransferase using the transformant. And a method for producing the same. [Effect] A levanfructotransferase gene is provided, and by using this gene, the levanfructotransferase can be produced in a large amount. Furthermore, mass production of difructose dianhydride IV using levan as a raw material is also possible. |
