Class of enzymes hydrolyzing disaccharides

β-Fructofuranosidase is an enzyme that catalyzes the hydrolysis (breakdown) of the table sugar sucrose into fructose and glucose.[1][2] Alternative names for β-fructofuranosidase EC 3.2.1.26 include invertase, saccharase, glucosucrase, β-fructosidase, invertin, fructosylinvertase, alkaline invertase, and acid invertase. The resulting mixture of fructose and glucose is called inverted sugar syrup. Related to invertases are sucrases. Invertases and sucrases hydrolyze sucrose to give the same mixture of glucose and fructose. Invertase is a glycoprotein that hydrolyses (cleaves) the non-reducing terminal β-fructofuranoside residues. Invertases cleave the O-C(fructose) bond, whereas the sucrases cleave the O-C(glucose) bond.[3] Invertase cleaves the α-1,2-glycosidic bond of sucrose.

For industrial use, invertase is usually derived from yeast. It is also synthesized by bees, which use it to make honey from nectar. The temperature o...
