Immobilization of mold beta-galactosidase
Collection of Czechoslovak Chemical Communications, 1988We immobilized beta-galactosidase (EC 3.2.1.23) from the mold Aspergillus oryzae by various methods on the derivatives of bead cellulose manufactured by Czechoslovak industry. The activity, specific activity and operational stability of the immobilized enzyme were determined.

Beta-Galactosidase Deficiency in the Hurler Syndrome
New England Journal of Medicine, 1969Abstract A deficiency of β-galactosidase (pH 5.0) was found in frozen tissues (brain, liver, kidney and spleen) from 10 patients with Hurler's syndrome (Types 1–3). The diminished activity of this enzyme was demonstrated with the use of nitrophenyl-galactosides as well as ganglioside GM1 and a "keratan sulfate-like" mucopolysaccharide.

Neuropathology and Applied Neurobiology, 1981Barnes I.C., Kelly D.F., Pennock C.A. & Randell J.A.J. (1981) Neuropathology and Applied Neurobiology 7, 463–476Hepatic beta galactosidase and feline GMI gangliosidosisThis paper describes the clinical, morphological and biochemical features of three cats with a progressive neurological disorder. Clinical features were ataxia and progressive tremor.

Beta-Galactosidase was partially restored by protease inhibitors, leupeptin, chymostatin and E-64 in cultured fibroblasts from three patients with beta-galactosidase-neuraminidase deficiency. Pepstatin did not activate this enzyme. Neuraminidase was not affected by any of these compounds in the culture medium.

Cold Spring Harbor protocols, 2010
When a transient or stable transfection assay is developed for a promoter, a primary objective is to quantify promoter strength. Because transfection efficiency in such assays can be low, promoters are commonly fused to heterologous reporter genes that encode enzymes that can be quantified using highly sensitive assays.

Endo-beta-galactosidases and keratanase.
Current protocols in molecular biology, 2008This overview covers the endo-beta-galactosidases; enzyme is capable of hydrolyzing a wide range of glycoconjugates. Endo-beta-galactosidases from numerous sources are discussed in terms of their substrate specificities and substrates, as well as their practical research applications.

Rabbit small intestinal beta-galactosidases.
American journal of veterinary research, 1984The beta-galactosidase activities of the rabbit small intestinal mucosa were studied over the pH range of 2.6 to 8.4, using different substrates, and in the presence or absence of the enzyme inhibitor p-chloromercuribenzoic acid. The results indicated the presence of 4 beta-galactosidases: (i) a neutral beta-galactosidase (lactase) with optimum pH of 5.
