Galactosidases
（重定向自Galactosidase）
Galactosidases are enzymes (glycoside hydrolases) that catalyze the hydrolysis of galactosides into monosaccharides.
If the galactoside is classified as an alpha-galactoside, the enzyme is called alpha-galactosidase, and if it is a beta-galactoside, it is called beta-galactosidase. Both varieties are categorized under the EC number 3.2.1.
