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-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。
