FUNCTION: Broad specificity glycosidase of the intestinal brush border membrane that hydrolyzes lactose, the main sugar in mammalian milk, to produce D-glucose and D-galactose (PubMed:3929764, PubMed:9762914, PubMed:12594539, PubMed:16400612).

FUNCTION: Broad specificity glycosidase of the intestinal brush border membrane that hydrolyzes lactose, the main sugar in mammalian milk, to produce D-glucose and D-galactose (PubMed:3929764, PubMed:9762914, PubMed:12594539, PubMed:16400612). The mature protein is composed of two domains that catalyze the hydrolysis of beta-glucopyranosides and beta-galactopyranosides, with a preference for hydrophilic aglycones (including lactose and cellobiose) for one domain and hydrophobic aglycones (like phlorizin and glycosylceramides) for the other (PubMed:3929764, PubMed:9762914, PubMed:12594539). {ECO:0000269|PubMed:12594539, ECO:0000269|PubMed:16400612, ECO:0000269|PubMed:3929764, ECO:0000269|PubMed:9762914}.
