Galactan 1,3-beta-galactosidase (EC 3.2.1.145, 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.
