Description
OverviewRecombinant, Bacteroides fragilis endo-β-galactosidase expressed in E. coli. Endo-β-Galactosidase is an enzyme that hydrolyzes internal β-galactosidic linkages of oligosaccharides in poly-N-acetyl-lactosamine structures. This enzyme resembles the Escherichia freundii enzyme due to its specificity towards bovine corneal keratan sulphate, milk oligosaccharides and the glycolipids lacto-N-neotetraosylceramide and lacto-N-tetraosylceramide.
