Novel Fructosyltransferases [PDF]

, 2001
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.

Structure-function analysis of plant fructosyltransferases [PDF]

, 2005
Fructans are an important class of plant carbohydrates that consist of linear or branched chains of fructosyl moieties. Their synthesis requires fructosyltransferases (FTs) that catalyze the transfer of fructosyl units from a donor substrate (sucrose ...

Transforming a Fructan:Fructan 6G-Fructosyltransferase from Perennial Ryegrass into a Sucrose:Sucrose 1-Fructosyltransferase [PDF]

Plant Physiology, 2009
Fructosyltransferases (FTs) synthesize fructans, fructose polymers accumulating in economically important cool-season grasses and cereals. FTs might be crucial for plant survival under stress conditions in species in which fructans represent the major ...

Recent advances in β-galactosidase and fructosyltransferase immobilization technology [PDF]

Critical Reviews in Food Science and Nutrition, 2020
The highly demanding conditions of industrial processes may lower the stability and affect the activity of enzymes used as biocatalysts. Enzyme immobilization emerged as an approach to promote stabilization and easy removal of enzymes for their ...

Safety evaluation of the food enzyme sucrose:sucrose fructosyltransferase from the genetically modified <i>Yarrowia lipolytica</i> strain E4772. [PDF]

EFSA J
Abstract The food enzyme sucrose:sucrose fructosyltransferase (sucrose:sucrose 1′‐β‐d‐fructosyltransferase; EC 2.4.1.99) is produced with the genetically modified Yarrowia lipolytica strain E4772 by SEQENS. The production strain met the requirements for the qualified presumption of safety (QPS) approach. The food enzyme is free from viable cells of the

Effect of temperature, pH and storage time on the stability of an extracellular fructosyltransferase from Aspergillus oryzae IPT-301

Brazilian Journal of Food Technology, 2021
In this work, it was determined the influence of temperature, pH and storage time on the enzymatic activity and stability of an extracellular fructosyltransferase (FTase E.C.2.4.1.9) from Aspergillus oryzae IPT-301 produced by submerged fermentation. The

Fructans Are Differentially Distributed in Root Tissues of Asparagus

Cells, 2020
Inulin- and neoseries-type fructans [fructooligosaccharides (FOS) and fructopolysaccharides] accumulate in storage roots of asparagus (Asparagus officinalis L.), which continue to grow throughout the lifespan of this perennial plant.

Fructooligosaccharides (FOS) Production by Microorganisms with Fructosyltransferase Activity

Fermentation, 2023
Fructans are fructose-based polymers, defined as fructooligosaccharides (FOS), when they possess a short chain. These molecules are highly appreciated in the food and pharmaceutical international market and have an increasing demand worldwide, mainly for

The large subunit determines catalytic specificity of barley sucrose:fructan 6‐fructosyltransferase and fescue sucrose:sucrose 1‐fructosyltransferase [PDF]

FEBS Letters, 2004
Plant fructosyltransferases are highly homologous in primary sequence and typically consist of two subunits but catalyze widely different reactions. Using functional expression in the yeast Pichia pastoris, we show that the substrate specificity of festuca sucrose:sucrose 1‐β‐d‐fructosyltransferase (1‐SST) and barley sucrose:fructan 6‐β‐d ...
