It is defined as "catalysis of the hydrolysis of terminal, non-reducing alpha-linked alpha-D-glucose residue with release of alpha-D-glucose." In this sense, "alpha-glucosidase" can encompass a wide range of enzyme activitiess, differing by the linkage of their terminal (1→3, 1→4, or 1→6), the specific identity of their substrate (sucrose ...
Alpha-glucosidase inhibitors (AGIs) are oral anti-diabetic drugs used for diabetes mellitus type 2 that work by preventing the digestion of carbohydrates (such as starch and table sugar). They are found in raw plants/herbs such as cinnamon and bacteria (containing the inhibitor acarbose ).
Beta-glucosidase # EC 3.2.1.21 : is associated with Gaucher's disease: Lactase: EC 3.2.1.23 : one member of the β-galactosidase family, breaks down milk sugars, and its absence in adulthood causes lactose intolerance: Debranching enzyme # EC 3.2.1.33: in mammals, yeast and some bacteria, combines transferase and glucosidase activity in ...
From these natural templates many other inhibitors have been developed, including isofagomine and deoxygalactonojirimycin, and various unsaturated compounds such as PUGNAc. Inhibitors that are in clinical use include the anti-diabetic drugs acarbose and miglitol, and the antiviral drugs oseltamivir and zanamivir. Some proteins have been found ...
Mechanism for cleaving of alpha-1,6 linkage. Amylo-α-1,6-glucosidase (EC 3.2.1.33), or glucosidase, cleaves the remaining alpha-1,6 linkage, producing glucose and a linear chain of glycogen. [10] The mechanism by which the glucosidase cleaves the α -1,6-linkage is not fully known because the amino acids in the active site have not yet been ...

Maltase-glucoamylase is an alpha-glucosidase digestive enzyme. It consists of two subunits with differing substrate specificity. Recombinant enzyme studies have shown that its N-terminal catalytic domain has highest activity against maltose, while the C-terminal domain has a broader substrate specificity and activity against glucose oligomers.

Glucan 1,6-α-glucosidase (EC 3.2.1.70, exo-1,6-β-glucosidase, glucodextrinase, glucan α-1,6-D-glucohydrolase) is an enzyme with systematic name glucan 6-α-D-glucohydrolase. [ 1 ] [ 2 ] [ 3 ] It catalyses the hydrolysis of (1→6)-α- D -glucosidic linkages in (1→6)-α- D -glucans and derived oligosaccharides
