α-Galactosidase ( EC 3.2.1.22, α-GAL, α-GAL A; systematic name α-D-galactoside galactohydrolase) is a glycoside hydrolase enzyme that catalyses the following reaction: [1] Hydrolysis of terminal, non-reducing α- D -galactose residues in α- D -galactosides, including galactose oligosaccharides, galactomannans and galactolipids
Galactosidases are enzymes (glycoside hydrolases) that catalyze the hydrolysis of galactosides into monosaccharides.. Galactosides can be classified as either alpha or beta. If the galactoside is classified as an alpha-galactoside, the enzyme is called alpha-galactosidase, and is responsible for catalyzing the hydrolysis of substrates that contain α-galactosidic residues, such as ...
Galactosidase alpha is an enzyme that in humans is encoded by the GLA gene. [5] Two recombinant forms of human α-galactosidase are called agalsidase alpha and agalsidase beta (INN). [6] A mold-derived form is the primary ingredient in gas relief supplements. [citation needed]
A person who inherits this gene does not have enough of a functioning enzyme known as alpha-galactosidase A. The lack of alpha-galactosidase leads to Fabry disease. A deficiency of alpha galactosidase A (a-GAL A, encoded by GLA) due to mutation causes a glycolipid known as globotriaosylceramide (abbreviated as Gb3, GL-3, or ceramide trihexoside ...
An active enzyme may be detected using artificial chromogenic substrate 5-bromo-4-chloro-3-indolyl-β-D-galactopyranoside, X-gal. β-galactosidase will cleave the glycosidic bond in X-gal and form galactose and 5-bromo-4-chloro-3-hydroxyindole which dimerizes and oxidizes to 5,5'-dibromo-4,4'-dichloro-indigo, an intense blue product that is ...
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 glycogen breakdown Pullulanase: EC 3.2.1.41 : has been used as a detergent
Beano contains the enzyme α-Galactosidase, specifically one derived from the fungus Aspergillus niger.The enzyme works in the digestive tract to break down the complex or branching sugars (polysaccharides and oligosaccharides) in foods such as legumes (beans and peanuts) and cruciferous vegetables (cauliflower, broccoli, cabbage, and brussels sprouts, among others).
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 ...
