Application Notes β-Galactosidase is useful for the structural investigation of carbohydrate, the determination of lactose (foodstuff analysis) and as an enzyme label for enzyme immunoassay.
Biochemical Physiological Actions 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.
