EC Molecular formula: EC 3.2.1.3

Product Overview: Produced via submerged fermentation of Aspergillus niger.  

Applications: Widely utilized in starch sugar production, alcohol manufacturing, brewing, and related industries.  

 

Unit Definition: One enzyme activity unit (U/mL) is defined as the quantity of enzyme required to hydrolyze 1 mg of starch per hour under standardized conditions (pH 4.6, 40°C).  

Mechanism of Action:  

Glucoamylase (EC 3.2.1.3), also termed amyloglucosidase or γ-amylase, is an exo-acting hydrolase that sequentially cleaves α-1,4-glycosidic bonds from the non-reducing termini of starch and glycogen molecules. This action releases β-D-glucose units via inversion of the anomeric configuration (α → β). While linear amylose substrates are nearly completely converted to glucose, branched substrates (e.g., amylopectin) yield glucose and residual α-1,6-linked oligosaccharides.
