The present invention relates to polypeptides, specifically polypeptides having transgalactosylating activity and nucleic acids encoding these, and their uses in e.g. dairy product.

Methods and compositions for a probiotic strain selected by targeted in vivo (in the human gut) enrichment to aid with healthy lactose digestion are provided. The probiotic strain selected may beneficially include Bifidobacterium adolescentis strain IVS-1 for reducing and/or preventing symptoms of lactose intolerance in a subject in need thereof.

Provided is a method for improving the production amount of a tri- or higher galactooligosaccharide and the reaction rate by a method for producing a galactooligosaccharide characterized by allowing β-galactosidase to react with a substrate in the presence of 5 to 60 mM sodium ions and 0.5 to 8 mM magnesium ions.

A composition formulated for intrathecal delivery of a recombinant adeno-associated virus (rAAV) vector comprising an AAVhu68 capsid carrying a human galactosylceramidase (GALC) gene for administration to Krabbe patients is provided. Also provided are novel gene sequences and uses thereof.

A spray-dried composition comprising an enzyme which is a β-galactosidase having transgalactosylating activity and a maltodextrin and/or sodium chloride.

The invention relates to carrier complexes and methods for delivering molecules to cells. The carrier complexes comprises a molecule and an aromatic cationic peptide in accordance with the invention. In one embodiment, the method for delivering a molecule to a cell comprises contacting the cell with a carrier complex. In another embodiment, the method for delivering a molecule to a cell comprises contacting the cell with a molecule and an aromatic cationic peptide.

The present invention relates to new improved peptide or dimeric peptides exhibiting betagalactosidase enzyme activity as well as improved methods for reducing the lactose content in compositions, such as dairy products.

The present invention relates to new improved peptide or dimeric peptides exhibiting betagalactosidase enzyme activity wherein the peptide has a pH optimum at acidic conditions.

The present invention provides a new type of galacto-oligosaccharide, having a mannose residue instead of a glucose residue at the reducing end. The invention also relates to compositions comprising this galacto-oligosaccharide, its preparation and use in nutritional compositions.

The usefulness of β-galactosidases derived from Bacillus circulans is further enhanced. A modified β-galactosidase in which one or more amino acids selected from the group consisting of proline 182 (P182), tyrosine 187 (Y187), serine 188 (S188), tryptophan 405 (W405), alanine 406 (A406), glutamine 407 (Q407), tyrosine 449 (Y449), threonine 483 (T483), serine 512 (S512), serine 531 (S531), threonine 533 (T533), serine 534 (S534), asparagine 550 (N550), glutamine 551 (Q551), tryptophan 593 (W593), tyrosine 598 (Y598), proline 602 (P602), proline 604 (P604), tyrosine 609 (Y609), lysine 612 (K612), and tyrosine 615 (Y615), or an amino acid(s) corresponding thereto, has/have been substituted by other amino acid in a β-galactosidase consisting of the amino acid sequence of any of SEQ ID NOs. 1 to 4 or an amino acid sequence having 90% or more identity to the amino acid sequence set forth in any of SEQ ID NOs. 1 to 4.
