Adsorption equilibrium of fructosyltransferase on a weak anion-exchange resin
Journal of Chromatography A, 2007The adsorption equilibrium of a glycoprotein, fructosyltransferase from Aureobasidium pullulans, on an anion-exchange resin, Sepabeads FP-DA activated with 0.1M NaOH, was investigated. The adsorption isotherms were determined at 20 degrees C in a phosphate-citrate buffer with pH 6.0 using the static method.

Enhanced production of fructosyltransferase in Aspergillus oryzae by genome shuffling
Biotechnology Letters, 2016To breed Aspergillus oryzae strains with high fructosyltransferase (FTase) activity using intraspecific protoplast fusion via genome-shuffling.A candidate library was developed using UV/LiCl of the conidia of A. oryzae SBB201. By screening for enzyme activity and cell biomass, two mutants (UV-11 and UV-76) were chosen for protoplast fusion and ...

Computational analysis of the fructosyltransferase enzymes in plants, fungi and bacteria
Gene, 2011Fructosyltransferases (FTases) are enzymes produced by plants, fungi, and bacteria, which are responsible for the synthesis of fructooligosaccharides. In this study, we conducted a computational analysis of reported sequences for FTase from a diverse source of organisms, such as plants, fungi, and bacteria.

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.
