  • Publication number: 20140066617
    Abstract: [Problem to be Solved] The importance of sugar chains having ?2,3- or ?2,6-linked sialic acid at their non-reducing ends is known. Industrial production has been demanded for these sugar chain compounds. Particularly, the production of glycoprotein drugs or the like inevitably requires producing in quantity sugar chains having homogeneous structures by controlling the linking pattern (?2,6-linkage or ?2,3-linkage) of sialic acid. Particularly, a triantennary or tetraantennary N-type complex sugar chain having sialic acid at each of all non-reducing ends is generally considered difficult to chemically synthesize. There has been no report disclosing that such a sugar chain was chemically synthesized. Furthermore, these sugar chains are also difficult to efficiently prepare enzymatically.

  • Publication number: 20130059332
    Abstract: The present invention relates to a process for the production of an aqueous glucose solution from maize or maize kernels. The invention also relates to a glucose solution obtainable by this process, and to its use for the production of organic compounds. The process according to the invention comprises: a) fractionating dry milling of maize kernels, where the maize kernels are separated into a maize-starch-comprising endosperm fraction and a high-oil germ fraction and, if appropriate, a bran fraction; b) enzymatic liquefaction and saccharification of the maize starch in an aqueous suspension of the endosperm fraction, which gives an aqueous glucose solution comprising maize gluten; and c) depletion of the maize gluten and, if appropriate, any bran present from the aqueous glucose solution.

  • Patent number: 8334115
    Abstract: A vector of the present invention has DNA encoding a protein or a product having the same effect as the protein, the protein containing an amino acid sequence from amino acid numbers 47 to 802 in SEQ. ID. NO:2. Expression of the DNA gives human chondroitin synthase. By using human chondroitin synthase, it is possible to produce a saccharide chain having a repeating disaccharide unit of chondroitin. The DNA or part thereof may be used as a probe for hybridization for the human chondroitin synthase.

  • Publication number: 20120296079
    Abstract: The present invention relates to a method for preparing enzymatically highly branched-amylose and amylopectin cluster. Alpha-glucanotransferase or branching enzyme hydrolyzes the linkage of the segment between amylopectin clusters in starch, producing amylopectin cluster, and simultaneously branching enzyme attaches the branched side-chain to amylose, producing branched amylose, and subsequently treating the amylopectin cluster or branched amylose with maltogenic amylase for cleaving long side chain into short side chain and for transferring glucose to the side chain, generating highly branched amylopectin cluster, highly branched amylose or branched oligosaccharide from starch effectively.

    Abstract: The present invention relates to a recombinant process for the production of truncated or mutated dextransucrases while conserving the enzymatic activity or their specificity in the synthesis of the ?-1,6 bonds. The present invention relates to nucleic acid sequences of truncated or mutated dextransucrases, vectors containing the nucleic acid sequences and host cells transformed by sequences encoding truncated or mutated dextransucrases. In another aspect, the invention concerns a method for producing, in a recombinant manner, truncated or mutated dextransucrases which conserve their enzymatic activity or which conserve their specificity in the synthesis of ?-1,6 bonds and can produce, from saccharose, dextrans with high molar mass and modified rheological properties compared with the properties of dextran obtained with the native enzyme and isomalto-oligosaccharides with a controlled molar mass and dextrans.
