Descrizione generale
β-Galactosidase is present in bacteria, fungi, yeast and animal organs. It is also found in fruits, such as apples, almonds and apricots. β-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 β-sandwich and fibronectin.
Applicazioni
β(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).
Azioni biochim/fisiol
β-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. β-Galactosidase is also applicable in the food industry to improve the sweetness, flavor and solubility.
Definizione di unità
