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
This article is about the enzyme. For the carbohydrate commonly called "alpha gal", see Galactose-alpha-1,3-galactose.

It catalyzes many catabolic processes, including cleavage of glycoproteins, glycolipids, and polysaccharides.
The enzyme is encoded by the GLA gene.[2] Two recombinant forms of human α-galactosidase are called agalsidase α (INN) and agalsidase β (INN). A mold-derived form is the primary ingredient in gas relief supplements.
