The invention provides variants of the Aspergillus japonicus β-fructofuranosidase enzyme which have been modified so as to improve synthesis of inulin-type fructooligosaccharides (FOS) from sucrose. One or more substitutions may be made to the parent β-fructofuranosidase polypeptide at amino acid positions (121, 159, 302 and/or 471) of the mature peptide (SEQ ID NO: 3), corresponding to crystal positions (140, 178, 321 and 490). A method of synthesising FOS using the variants is also claimed.

摘要:
The present invention relates to genetically engineered organisms, especially microorganisms such as bacteria and yeasts, for the production of added value bio-products such as specialty saccharide, activated saccharide, nucleoside, glycoside, glycolipid or glycoprotein. More specifically, the present invention relates to host cells that are metabolically engineered so that they can produce said valuable specialty products in large quantities and at a high rate by bypassing classical technical problems that occur in biocatalytical or fermentative production processes.
