The present invention relates to a method of producing a polypeptide having ?-hexosaminidase activity, comprising the steps of a) providing a yeast cell comprising a polynucleotide encoding a polypeptide having ?-hexosaminidase activity and having an amino acid sequence being at least 95% identical to the amino acid sequence shown in SEQ ID NO: 1, b) cultivating said yeast cell under conditions which allow for the production of the polypeptide, and c) obtaining the polypeptide produced in step b). The present invention further concerns a polynucleotide encoding a polypeptide having ?-hexosaminidase activity and having an amino acid sequence being at least 95% identical to the amino acid sequence shown in SEQ ID NO: 1, as well as polypeptide encoded by said polynucleotide. Moreover, the present invention concerns a yeast cell comprising the polynucleotide of the present invention.

The invention provides modular cell-free de-novo synthesis of glycans with immobilized bionanocatalysts. The invention provides materials, and in particular, magnetic materials, for producing glycans of defined length and sequences using one or more enzymes that are immobilized within bionanocatalysts (BNCs) which in turn are embedded within scaffolds to control the synthesis in batch or continuous processes manufacturing. In some embodiments, the scaffolds are high magnetism and high porosity composite blends of thermoplastics or thermosets comprising magnetic particles that form powders. In some embodiments, Selective Laser Sintering (SLS) is used to design and produce objects via 3D printing by sintering composite magnetic powders. The modular flow cells may be mixed and matched for a highly customizable and highly efficient cell-free manufacturing process. In some embodiments the elementary and system modules provided by the invention are employed. In preferred embodiments, human milk oligosaccharides (HMOs) are produced.

The present invention relates to polypeptides having hexosaminidase activity, and polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

Provided is a modified -subunit of human -hexosaminidase which has the activity derived from the -subunit of wild-type human -hexosaminidase and has the resistance to protease. A protein comprising an amino acid sequence having substitutions of the 312th to the 318th amino acids with glycine, serine, glutamic acid, proline, serine, glycine and threonine in order, respectively, in an amino acid sequence of a -subunit of wild-type human -hexosaminidase.

Disclosed is a method for producing a glycoprotein using mammalian cells, wherein all or part of the non-reducing ends of N-glycoside binding sugar chains are mannose residues. The method is a method for producing glycoproteins using transformant mammalian cells which are prepared by introducing thereinto a -N-acetylglucosaminidase gene and inducing its expression.

The present invention relates to a detergent preparation containing, relative to the total weight thereof, a hexosaminidase preparation and 0.5 to 10 wt % of a polyalkoxylated amine having a weight-average molecular weight M.sub.w in the range of 600 g/mol to 10,000 g/mol, which is obtainable by reacting ammonia or primary alkyl or hydroxyalkylamines having a molecular weight of less than 200 g/mol with alkylene oxides; and textile washing methods using this detergent preparation.

Methods to introduce highly phosphorylated mannopyranosyl oligosaccharide derivatives containing mannose-6-phosphate (M6P), or other oligosaccharides bearing other terminal hexoses, to carbonyl groups on oxidized glycans of glycoproteins while retaining their biological activity are described. The methods are useful for modifying glycoproteins, including those produced by recombinant protein expression systems, to increase uptake by cell surface receptor-mediated mechanisms, thus improving their therapeutic efficacy in a variety of applications.
