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
Alpha-galactosidase (EC 3.2.1.22) (melibiase) [8] catalyzes the hydrolysis of melibiose into galactose and glucose. In man, the deficiency of this enzyme is the cause of Fabry's disease (X-linked sphingolipidosis). Alpha-galactosidase is present in a variety of organisms.
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 ...
Pegunigalsidase alfa, sold under the brand name Elfabrio, is an enzyme replacement therapy for the treatment of Fabry disease. [2] [4] It is a recombinant human α-galactosidase-A. [4] It is a hydrolytic lysosomal neutral glycosphingolipid-specific enzyme. [2] The most common side effects are infusion-related reactions, hypersensitivity and ...
Two recombinant enzyme replacement therapies are available to functionally compensate for α-galactosidase deficiency. Agalsidase α and β are both recombinant forms of the human α-galactosidase A enzyme and both have the same amino acid sequence as the native enzyme. Agalsidase α and β differ in the structures of their oligosaccharide side ...
Why Are Some Dogs Lactose Intolerant? Since puppies drink their mother's milk, their bodies produce lactase, an enzyme that helps them digest the lactose sugars found in milk. Once they are weaned ...
Escherichia coli alpha-galactosidase (gene melA), which requires NAD and magnesium as cofactors, is not structurally related to the eukaryotic enzymes; by contrast, an Escherichia coli plasmid encoded alpha-galactosidase (gene rafA 9] contains a region of about 50 amino acids which is similar to a domain of the eukaryotic alpha-galactosidases.
