The Journal of the Science of Food and Agriculture
BACKGROUND Fructo-oligosaccharide (FOS) belongs to the group of short inulin-type fructans and is one of the most important non-digestible bifido-oligosaccharides capable of biotransforming sucrose using fructosyltransferases (FTase).

Microbial production of fructosyltransferases for synthesis of pre-biotics
Biotechnology Letters, 2008Fructooligosaccharides (FOS) are prebiotic substances found in several vegetable or natural foods. The main commercial production of FOS comes from enzymatic transformation of sucrose by the microbial enzyme fructosyltransferase. The development of more efficient enzymes, with high activity and stability, is required and this has attracted the interest

Expression and Activity Analysis of Fructosyltransferase from Aspergillus oryzae
The Protein Journal, 2017The fructosyltransferase gene was isolated and cloned from Aspergillus oryzae. The gene was 1368 bp, which encoded a protein of 455 amino acids. To analyze the activity of the expressed fructosyltransferase, the pET32a-fructosyltransferase recombined plasmid was transformed into Escherichia coli BL21.

Isolation and characterization of fructosyltransferase from chicory roots
Phytochemistry, 1971Abstract The occurrence of fructosyltransferase was demonstrated in the roots of chicory. The enzyme was purified 14-fold by ammonium sulphate fractionation and sephadex column chromatography. The optimal conditions for activity were pH 5·6, 37° and substrate (sucrose) concentration of 5·84 × 10 −1 M.

The present invention describes two novel proteins having fructosyltransferase activity. Both enzymes are derived from lactobacilli, which are food-grade microorganisms with the Generally Recognized As Safe (GRAS) status. One of these proteins produces an inulin and fructo-oligosaccharides, while the other produces a levan.

Purification and kinetic characterization of a fructosyltransferase from Aspergillus aculeatus
Journal of Biotechnology, 2007A fructosyltransferase present in Pectinex Ultra SP-L, a commercial enzyme preparation from Aspergillus aculeatus, was purified to 107-fold and further characterised. The enzyme was a dimeric glycoprotein (20% (w/w) carbohydrate content) with a molecular mass of around 135 kDa for the dimer.

Expression of fructosyltransferase genes in transgenic plants
1999Fructans serve as a carbohydrate reserve in many plant species and are also synthesised by several microorganisms. Over the past decade interest in the use of fructans for food and non-food applications has increased exponentially. Our interest is to modify crops for the production of tailor-made fructans.
