Description
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. Two recombinant forms of alpha-galactosidase are called agalsidase alfa (INN) and agalsidase beta (INN).

Unit Definition
One unit is defined as the amount of enzyme required to release 1 μmol of p-nitrophenol per minute from p-nitrophenyl-α-D-Dgalactopyranoside (1 mM in the assay) in 25 mM Tris-HCl buffer, Ph 8.5, at 37°C.
Optimum pH
8.5
