EC 3.2.1.3 : is a digestive enzyme Cellulase # EC 3.2.1.4 : breaks down cellulose from plant material Sucrase-isomaltase: EC 3.2.1.10 - Mannosyl-oligosaccharide glucosidase # EC 3.2.1.106 catalyzes the first trimming step of the N-glycosylation pathway; is associated with Congenital Disorder of Glycosylation type IIb: Acid α-glucosidase # EC 3 ...
α-Glucosidase hydrolyzes terminal non-reducing (1→4)-linked α-glucose residues to release a single α-glucose molecule. [ 10 ] α-Glucosidase is a carbohydrate-hydrolase that releases α-glucose as opposed to β-glucose. β-Glucose residues can be released by glucoamylase, a functionally similar enzyme.
Chemically, the drug is an analog of the enzyme that is deficient in patients affected by Pompe disease, alpha-glucosidase. It is the first drug available to treat this disease. [2] It was approved for medical use in the United States in April 2006, as Myozyme [7] and in May 2010, as Lumizyme. [8]
[1] [2] Carbohydrates are normally converted into simple sugars (monosaccharides) by alpha-glucosidase enzymes present on cells lining the intestine, enabling monosaccharides to be absorbed through the intestine. Hence, alpha-glucosidase inhibitors reduce the impact of dietary carbohydrates on blood sugar. [3] [1]
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 1,4-α-glucosidase (EC 3.2.1.3, glucoamylase, amyloglucosidase, γ-amylase, lysosomal α-glucosidase, acid maltase, exo-1,4-α-glucosidase, glucose amylase, γ-1,4-glucan glucohydrolase, acid maltase, 1,4-α-D-glucan glucohydrolase) is an enzyme located on the brush border of the small intestine with systematic name 4-α-D-glucan ...
Glucan 1,3-α-glucosidase (EC 3.2.1.84, exo-1,3-α-glucanase, glucosidase II, 1,3-α-D-glucan 3-glucohydrolase) is an enzyme with systematic name 3-α-D-glucan 3-glucohydrolase. [1] It catalyses the hydrolysis of terminal (1→3)-α-D-glucosidic links in (1→3)-α-D-glucans. It does not act on nigeran although it has some activity against ...
The enzyme GDP-glucosidase (EC 3.2.1.42) catalyzes the chemical reaction GDP-glucose + H 2 O ⇌ {\displaystyle \rightleftharpoons } D -glucose + GDP Thus, the two substrates of this enzyme are GDP-glucose and H 2 O , whereas its two products are D -glucose and GDP .
