Galactan 1,3-beta-galactosidase
Ec Number:	3.2.1.145
Cas Number:	161515-48-6

Galactan 1,3-beta-galactosidase (galactan (1->3)-beta-D-galactosidase) is an enzyme with systematic name galactan 3-beta-D-galactosidase.^{[1] [2]} This enzyme catalyses the following chemical reaction

Hydrolysis of terminal, non-reducing beta-D-galactose residues in (1->3)-beta-D-galactopyranans

This enzyme removes not only free galactose, but also 6-glycosylated residues.
