Abstract
A &bgr;-fructofuranosidase gene coding for a protein having an amino acid sequence described in Seq. I.D. No. 1 in the Sequence Listing. The gene enables production of &bgr;-fructofuranosidase on a large scale more easily and less dependently on the productivity of microorganisms than the production by cultivation of the microorganisms. Also, the &bgr;-fructofuranosidase gene is useful for the development of variant enzymes that have increased heat resistance and transfer ratio by means of genetic engineering techniques.
