General description【一般描述】	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.
Application【应用】	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【生化/生理作用】	β-Galactosidase acts on the terminal β-D-galactosyl moieties of disaccharides, glycoconjugates, and polysaccharides. It is useful in mediating transglycosylation reactions such as the synthesis of galactooligosaccharides (GOS). β-Galactosidases might be used for glycobiological and biotechnological applications. β-半乳糖苷酶切割乳糖成单糖成分，葡萄糖和半乳糖。它还能催化葡萄糖转糖基化形成异乳糖，在反馈回路中作为β-半乳糖苷酶的诱导剂。
Unit Definition【单位定义】	一单位每分钟水解1.0 μmole乳糖，pH4.5,30℃。
