Gosset Beta-fructofuranosidase Overview
Beta-fructofuranosidase (EC 3.2.1.26), also commonly called invertase, is an enzyme that catalyzes the hydrolysis of sucrose into glucose and fructose by cleaving the terminal non-reducing β-D-fructofuranoside residues in β-D-fructofuranosides[2][3][10]. It is widely used in the food industry for the production of invert sugar syrups, in baking, for sucrose-based fermented beverages, and other processes[2][3]. The most common industrial source is the yeast Saccharomyces cerevisiae, though it can also be produced by various fungi and bacteria[6][9]. The enzyme is generally recognized as safe, with a very low risk of allergenicity though cross-reactivity in tomato-allergic individuals has been documented[3][5]. It is not a direct therapeutic target in medicine but is crucial industrially for carbohydrate modification and processing.
Mechanism of Action
Catalyzes the hydrolysis of terminal non-reducing β-D-fructofuranoside residues in β-D-fructofuranosides, mainly sucrose, releasing fructose and glucose[1][2][10].
Biological Functions
Disease Associations
Safety Considerations
- Potential allergenicity, especially in individuals with tomato allergy, but overall risk is considered low[3][5].
- There are no significant toxicological concerns in food or industrial applications[3][4][5].
