BETA FRUCTOFURANOSIDASE MUTANT

摘要

An object of the present invention is to provide a ²-fructofuranosidase variant whose reaction specificity is improved to be suitable for the production of fructooligosaccharides. According to the present invention, there is provided a ²-fructofuranosidase variant consisting of a mutated amino acid sequence of SEQ ID NO: 2 or a mutated homologue thereof, which has mutations at specific amino acid residues.
