Hydrolyzes oligosaccharides released by the endo-1,4-beta-galactosidase GalA from arabinogalactan type I, a pectic plant polysaccharide. It is unable to use lactose as a sole carbon source (By similarity). Catalyzes the hydrolysis of lactose to its constituent monosaccharides glucose and galactose. Possesses a low level of transgalactosylation activity for the production of galacto-oligosaccharides (GOS) from lactose.

Belongs to the glycosyl hydrolase 42 family.
