Molecular and functional characterization of novel fructosyltransferases and invertases from Agave tequilana.

PLoS ONE, 2012
Fructans are the main storage polysaccharides found in Agave species. The synthesis of these complex carbohydrates relies on the activities of specific fructosyltransferase enzymes closely related to the hydrolytic invertases. Analysis of Agave tequilana

Linking expression of fructan active enzymes, cell wall invertases and sucrose transporters with fructan profiles in growing taproot of chicory (Cichorium intybus): Impact of hormonal and environmental cues

Frontiers in Plant Science, 2016
In chicory taproot, the inulin-type fructans serve as carbohydrate reserve. Inulin metabolism is mediated by fructan active enzymes (FAZYs): sucrose:sucrose 1-fructosyltransferase (1-SST; fructan synthesis), fructan:fructan-1-fructosyltransferase (1-FFT;

In vitro binding interactions of oral bacteria with immobilized fructosyltransferase [PDF]

Journal of Applied Microbiology, 2006
The objective of the present study was to explore the role of immobilized fructosyltransferase (FTF) in adhesion process.We investigated real-time biospecific interactions between several types of oral bacteria and recombinant FTF immobilized on a biosensor chip, using surface plasmon resonance technology.

Characterization of the Fructosyltransferase Gene of Actinomyces naeslundii WVU45 [PDF]

Journal of Bacteriology, 2000
ABSTRACT Oral actinomycetes produce fructosyltransferase (FTF) enzymes which convert sucrose into polymers of d -fructose, known as levans, and these polymers are thought to contribute to the persistence and virulence of the organisms.

Achieving protease substrate‐specific inhibition by mAb dual functional selections

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Proteases are promiscuous enzymes acting on multiple substrates. Inhibiting pathogenic proteolysis while sparing physiological ones is essential for the development of effective and safe inhibitors. By engineering β‐lactamase and levansucrase as selection and counterselection markers in E.

Purification and Characterization of the Enzymes of Fructan Biosynthesis in Tubers of Helianthus tuberosus Colombia (II. Purification of Sucrose:Sucrose 1-Fructosyltransferase and Reconstitution of Fructan Synthesis in Vitro with Purified Sucrose:Sucrose 1-Fructosyltransferase and Fructan:Fructan 1-Fructosyltransferase) [PDF]

Plant Physiology, 1996
Sucrose:sucrose 1-fructosyltransferase (1-SST), an enzyme involved in fructan biosynthesis, was purified to homogeneity from tubers of Helianthus tuberosus that were harvested in the accumulation phase. Gel filtration under native conditions predicted a molecular mass of about 67 kD. Electrophoresis or gel filtration under denaturing conditions yielded

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 24: Suitability of taxonomic units notified to EFSA until March 2026

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.

Fermentation by Probiotic Lactobacillus gasseri Strains Enhances the Carotenoid and Fibre Contents of Carrot Juice

Foods, 2020
Carrot juice (straight, 8.5 Brix and concentrated, 15.2 Brix) was fermented by lactic acid bacteria (Lactobacillus gasseri strain DSM 20604 or DSM 20077). Fermentation enhanced the nutritional profile of carrot juice. There was a greater sugar reduction (

Safety evaluation of an extension of use for the food enzyme β‐fructofuranosidase from the genetically modified Trichoderma reesei strain AR‐996 and amended specifications for its use as a food additive invertase (E1103)

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The food enzyme β‐fructofuranosidase (β‐D‐fructofuranoside fructohydrolase; EC 3.2.1.26) is produced with the genetically modified (GM) Trichoderma reesei strain AR‐996 by AB Enzymes. The safety of this food enzyme was evaluated previously, and it did not give rise to safety concerns when used in three food manufacturing processes ...
