Alpha-galactosidase is a glycoside hydrolase enzyme that hydrolyses the terminal alpha-galactosyl moieties from glycolipids and glycoproteins. It is encoded by the GLA gene.[1] Two recombinant forms of human alpha-galactosidase are called agalsidase alpha (INN) and agalsidase beta (INN). A mold-derived form is the primary ingredient in gas relief supplements.
Function
This enzyme is a homodimeric glycoprotein that hydrolyses the terminal alpha-galactosyl moieties from glycolipids and glycoproteins. It predominantly hydrolyzes ceramide trihexoside, and it can catalyze the hydrolysis of melibiose into galactose and glucose.
Pathology
A variety of mutations in this gene affect the synthesis, processing, and stability of this enzyme, which causes Fabry disease, a rare lysosomal storage disorder and sphingolipidosis that results from a failure to catabolize alpha-D-galactosyl glycolipid moieties.[2]
Two enzyme replacement therapies are available to functionally compensate for alpha-galactosidase deficiency. Agalsidase alpha and beta are both recombinant forms of the human α-galactosidase A enzyme and both have the same amino acid sequence as the native enzyme. Agalsidase alpha and beta differ in the structures of their oligosaccharide side chains.[3]
Agalsidase alpha
The pharmaceutical company Shire manufactures agalsidase alfa (INN) under the trade name Replagal as a treatment for Fabry disease,[4] and was granted marketing approval in the EU in 2001.[5] FDA approval was applied for the United States.[6] However, in 2012, Shire withdrew their application for approval in the United States citing that the agency will require additional clinical trials before approval.[7]
Agalsidase beta
The pharmaceutical company Genzyme produces synthetic agalsidase beta (INN) under the trade name Fabrazyme for treatment of Fabry disease. In 2009, contamination at Genzyme's Allston, Massachusetts plant caused a worldwide shortage of Fabrazyme, and supplies were rationed to patients at one-third the recommended dose. Some patients have petitioned to break the company's patent on the drug under the "march-in" provisions of the Bayh–Dole Act.[6]
Over-the-counter brand names
Alpha-galactosidase derived from aspergillus niger (a common mold) is an active ingredient in products marketed to reduce stomach gas production after eating foods known to cause gas. It is optimally active at 55 degrees C, after which its half-life is 120 minutes.[8]
There are scores of supplements containing the enzyme over the counter in the United States and many more world wide. Products with Alpha-galactosidase include:
- Beano
- CVS BeanAid
- Enzymedica's BeanAssist
- Solaray's supplement "DopaBean"
- Gasfix

- Beta-galactosidase
