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.

应用

β-Galactosidase fromAspergillus oryzaehas been used:

• inin vitronuclear 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

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。

单位定义

一单位每分钟水解1.0 μmole乳糖，pH4.5,30℃。
