Fructosyltransferase
![]()

Fructosyltransferase is a specialized enzyme belonging to the glycosyltransferase family.
It catalyzes the transfer of fructosyl groups from a donor molecule, such as sucrose, to an acceptor substrate, forming fructose-containing polymers or oligosaccharides.
Fructosyltransferase is widely studied for its role in carbohydrate metabolism and its industrial potential in biotechnology, food science, and healthcare.
Biosynthesis of Fructans: Fructosyltransferase plays a central role in synthesizing fructans—polymers of fructose—in plants and microorganisms. These fructans serve as energy reserves and stress-response molecules.
Microbial Biofilm Formation: In oral bacteria like Streptococcus mutans, Fructosyltransferase converts sucrose into extracellular polysaccharides, contributing to dental plaque formation.
Prebiotic Production: Industrially, Fructosyltransferase is harnessed to produce prebiotic compounds like fructooligosaccharides (FOS), which promote gut health by stimulating beneficial microbiota.
