α-Galactosidase (EC 3.2.1.22) (EC 3.2.1.22), that is, α-galactosidase, is a glycoside hydrolase that widely exists in animals, plants and microorganisms, and is often used in biochemical research. α-Galactosidase catalyzes the hydrolysis of α-1,6-linked terminal galactose residues, including galactooligosaccharides, galactomannans, and galactolipids. Catalyzes many catabolic processes including cleavage of glycoproteins, glycolipids and polysaccharides^[1].
