应用
β-Galactosidase from bovine testes was used for coupling to Sepharose.
生化/生理作用
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.
外形
Suspension in 3.2 M (NH4)2SO4, pH approx. 5.0
其他说明
One unit will hydrolyze 1.0 μmole of p-nitrophenyl β-D-galactopyranoside to p-nitrophenol and D-galactopyranose per min at pH 4.4 at 25 °C.
