Description générale

Amyloglucosidase is synthesized by several Aspergillus genus species. It is a disaccharidase–type α-glucosidase. This enzyme is an exo-enzyme and one of the major industrial enzymes. The stability of amyloglucosidase can be increased by immobilization.

Spécificité

Cleaves terminal glucoses that are α1,4- or α1,6-linked to an oligo- or polysaccharide of multiple glucose units. The product is D-glucose.
Heat inactivation: Heat inactivation is recommended at 80 °C for 45 minutes, followed by rapidly cooling down.

Application

Amyloglucosidase from Aspergillus niger can be used for the hydrolyzation of terminal α1,4- and α1,6-glucosidic bonds (glucose-glucose bonds) in polysaccharides (e.g., starch, dextrins, glycogen), removing glucose units sequentially from the non-reducing end of the molecule. The enzyme will also cleave maltose and maltosides (maltotriose, maltotetraose, etc.).

Actions biochimiques/physiologiques

Amyloglucosidase from Aspergillus niger is capable of hydrolyzing the α-D-(1-4), the α-D-(1-6), and the α-D-(1-3) glucosidic bonds of oligosaccharides. Amyloglucosidase is an extracellular enzyme that converts starch to dextrins and glucose. The enzyme is used in the starch-processing industry for the commercial production of D-glucose from corn syrups.

Définition de l'unité

Unit Conversion: One unit (+25 °C; glycogen as substrate) corresponds to 8.6 U (+60 °C; starch as substrate).

Forme physique

Suspension in 3.2 M ammonium sulfate solution, pH approximately 6
