| Application: | β-Galactosidase from Aspergillus oryzae has been used: • in in vitro nuclear magnet resonance (NMR) • as a standard in the β-galactosidase assay to determine the concentration of cell-associated β-galactosidase • to modify sugar residues on the surface of the mutant slime cells to study the adhesive properties • for enzymatic hydrolysis of lactose • for reversed-phase (RP) adsorption • in the hydrolysis of whey lactose |
| Biochem/physiol Actions: | β-Galactosidase acts on the terminal β- |
| Biochem/physiol Actions: | β-galactosidase cleaves lactose into its monosaccharide components, glucose and galactose. It also catalyses the transglycosylation of glucose into allolactose, the inducer of β-galactosidase, in a feedback loop. |
| General description: | β-Galactosidase is a member of the glycoside hydrolase clan A (GH-A) family. It is widely present in microorganisms, which includes both prokaryotes and eukaryotes. |
| Other Notes: | One unit will hydrolyze 1.0 μmole of lactose per minute at pH at 4.5 at 30 °C. |
