Glucosidases

Glucosidases are a group of enzymes that split off the single sugar glucose (grape sugar) from the double and multiple sugars . Glucosidases are a subgroup of the glycosidases .

The hydrolytic cleavage of the glycosidically bound glucose by glucosidases takes place from the non-reducing chain end of the saccharides or from glycosides . A distinction is made between α-glucosidases and β-glucosidases . α-glucosidases such as amylases , saccharase and maltases split off α-glycosidically bound glucose; β-glucosidases split off β-glycosidically bound glucose.

Glucosidases are widespread in animals and plants as well as in microorganisms . They are rather unspecific and usually able to process several substrates at different speeds.
