产品说明
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 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
包装
25000, 125000, 500000 units in poly bottle
生化/生理作用
β-Galactosidase acts on the terminal β-
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℃。
