Galactosidases

Galactosidases are enzymes (glycoside hydrolases) which catalyzes the hydrolysis of galactosides into monosaccharides

If the galactoside is 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.
