β-Glucosidases (3.2.1.21) are found in all domains of living organisms, where they play essential roles in the removal of nonreducing terminal glucosyl residues from saccharides and glycosides. β-Glucosidases function in glycolipid and exogenous glycoside metabolism in animals, defense, cell wall lignification, cell wall β-glucan turnover, phytohormone

Glucosidases and exo-glucanases
Canadian Journal of Biochemistry, 1968A comparison was made of exo-α-glucanases with α-glucosidases, and of exo-β1 → 3-glucanases with β-glucosidases to establish criteria for their characterization. Dimers, trimers, and tetramers of glucose are substrates for both exo-glucanases and glucosidases. Exo-glucanases act more rapidly on the longer oligomers, glucosidases on the shorter.

Immobilization of ?-D-Glucosidase and ?-D-Glucosidase-polyphenolic complexes
Biotechnology Letters, 1983β-D-Glucosidase, alone and after copolymerizing with a resorcinol polymer, was immobilized on a PM 10 ultrafiltration membrane, κ-carrageenan and DEAE (DE52) cellulose. The best support for both enzyme preparations, in terms of high Vmax values, was the ultrafiltration membrane.

A simple kinetic test to distinguish exo-glucosidase and β-glucosidase activities
Biochemical and Biophysical Research Communications, 1985Unusual kinetic behaviour was observed in assaying spectrophotometrically for exo-glucanase activity in a beta-glucosidase isolated from A. faecalis using p-nitrophenyl beta-cellobioside as substrate. At high substrate concentrations no phenol was released whereas at low concentrations a rapid release of phenol was detected and this increased in rate ...

Alpha-glucosidase inhibitors are antihyperglycemic agents that lower blood glucose by delaying the digestion and absorption of complex carbohydrates. They are competitive inhibitors of the enzymes in the brush border of enterocytes that cleave eligosaccharides to monosaccharides.

Abstract Initial studies on partially purified a-glucosidase I from rat liver1·2 and oviduct microsomes3 .4 demonstrated that this enzyme removes a single glucose residue from Glc3Man9GlcNAc2. a-Glucosidase I was subsequently purified from calf5 and porcine6 liver, lactating bovine mammary tissue7, mung bean seedlings8, and 5 ...

Glucosidases and galactosidases in soils
Soil Biology and Biochemistry, 1988Abstract An improved method to assay activities of α- and β-glucosidases and α- and β-galactosidases in soils is described. It involves extraction and colorimetric determination of the p-nitrophenol released when 1 g of soil is incubated with 5 ml of buffered p-nitrophenyl glycoside solution at 37°C for 1 h.

On the Glucosidases of the Intestine of the Pig.
Acta Physiologica Scandinavica, 1943Summary.An investigation is made of the glucosidases of the small intestine and the duodenum of the pig. It is shown that both α‐and β‐glucosidase occur, and the pH‐activity curves of both enzymes are determined.

Reversible inhibitors of .beta.-glucosidase
Biochemistry, 1985A variety of reversible inhibitors of sweet almond beta-glucosidase were examined. These included simple sugars and sugar derivatives, amines and phenols. With respect to the sugar inhibitors and, indeed, the various glycoside substrates, the enzyme has what can be considered a "relaxed specificity".
