Abstract
A novel &bgr;-fructofuranosidase gene and a &bgr;-fructofuranosidase encoded by the gene, a process for isolating a &bgr;-fructofuranosidase gene using the novel &bgr;-fructofuranosidase gene, and a novel &bgr;-fructofuranosidase obtained by this isolation process are disclosed. A novel mold fungus having no &bgr;-fructofuranosidase activity suitable for the production of &bgr;-fructofuranosidase, and a system for producing a recombinant &bgr;-fructofuranosidase using the novel mold fungus as a host is disclosed. Further, a &bgr;-fructofuranosidase variant which selectively and efficiently produces a specific fructooligosaccharide such as 1-kestose from sucrose is disclosed.
