A few are evolved beta-galactosidase (EBG), beta-glucosidase , 6-phospho-beta-galactosidase, beta-mannosidase, and lactase-phlorizin hydrolase. (wikidoc.org)
About 70% of the adult world population is lactose-intolerant, due to low levels of intestinal lactase, also called lactase-phlorizin hydrolase (LPH), a β-D-galactosidase found in the apical surface of the intestinal microvilli. (researchgate.net)
Enzyme3
β-galactosidase , also called lactase , beta-gal or β-gal , is a glycoside hydrolase enzyme that catalyzes the hydrolysis of β-galactosides into monosaccharides through the breaking of a glycosidic bond . (wikidoc.org)
Many adult humans lack the lactase enzyme, which has the same function of beta-gal, so they are not able to properly digest dairy products. (wikidoc.org)
Beta-galactose is used in such dairy products as yogurt, sour cream, and some cheeses which are treated with the enzyme to break down any lactose before human consumption. (wikidoc.org)
Structure2
The 1,024 amino acids of E. coli β-galactosidase were first sequenced in 1970, [7] and its structure determined twenty-four years later in 1994. (wikidoc.org)
Comparison between the effect on the L3 phase of encapsulated beta-galactosidase (238 kDa), aspartic protease (34 kDa), myoglobin (17.6 kDa) and phytoglobin BvPgb 1.2 (38.4 kDa) demonstrated the importance of specific lipid-protein interactions on the L3 structure both in bulk and dispersions, as well as the stability of the encapsulated proteins.

Coli1
beta-Galactosidase/anti-beta-galactosidase complexes were made using a monoclonal antibody raised against bacterial (E. coli) beta-galactosidase and enzyme activity was quantified with a fluorogenic substrate. (ox.ac.uk)
