Application

?(1?4)-Galactosidase, positionally specific from Streptococcus pneumonia has been used:as a position-specific enzyme to study its effects in the terminal galactosylation with protective efficacy of glycosphingolipid (GSPL) in mice.for the digestion of radioactive oligosaccharides.as a position-specific enzymeto study its effects on the virulence profile of avirulent Leishmania donovani clone (A-LD).

Biochem/physiol Actions

?-Galactosidase plays a role in hydrolyzing the D-galactosyl moieties in oligosaccharides, polymers and secondary metabolites. It is widely applicable in the dairy industry to remove lactose from milk and dairy products for the benefit of lactose-intolerant individuals. ?-Galactosidase is also applicable in the food industry to improve the sweetness, flavor and solubility.

General description

?-Galactosidase is present in bacteria, fungi, yeast and animal organs. It is also found in fruits, such as apples, almonds and apricots. ?-Galactosidase is a tetramer and is made up of four polypeptide chains consisting of amino acids that assemble to form five structural domains. The domains are jelly roll barrel, a central domain that serves as an active site and the remaining domains are composed of ?-sandwich and fibronectin.

Physical form

Solution in 20 mM Tris-HCl, pH 7.5, 25 mM NaCl

Unit Definition
