  • Patent number: 10053682
    Abstract: The present invention relates to the field of genetic engineering and hereditary engineering. The present invention discloses a ?-galactosidase (?-galactoside galactohydrolase, EC 3.2.1.23) mutant with high transglycosidase activity, which is obtained by single-site-saturation mutation of amino acid sequences of ?-galactosidase from Aspergillus candidus and Aspergillus oryzae, with own signal peptides removed. The transglycosidase activity of the mutant is over 15% higher than that of wild types. Meanwhile, the present invention also discloses a DNA molecule which encodes the mutant, a recombinant expression vector containing the DNA molecule, and a host cell expressing the DNA molecule. In addition, the present invention also provides a method for preparing ?-galactosidase mutant with high transglycosidase activity by using the recombinant expression vector and applications of the mutant, the DNA molecule, the recombinant expression vector and the host cell in preparation of ?-galactosidase.

  • Publication number: 20140057335
    Abstract: The present invention is directed generally to cell culture media useful for introducing macromolecules and compounds (e.g., nucleic acid molecules) into cells (e.g., eukaryotic cells in the presence of said media. Cells containing introduced materials can be further cultured in the media. In particular, the invention allows introduction of nucleic acid molecules (e.g., vectors) into cells (particularly eukaryotic cells) and expression of proteins encoded by the nucleic acid molecules in the cells. The invention obviates the need to change the cell culture medium each time a different procedure is performed with the cells (e.g., culturing cells vs. transfecting cells). The invention thus provides efficient and high throughput methods to transform/transfect culture and cells avoiding the need for multiple manipulations and transfers of cells during transfection and expression studies.

  • Patent number: 8354259
    Abstract: A system and method capable of hydrolyzing lactose, where the system includes a support formed from a functionalized hydrophobic polymer that is covalently linked to a hydrophilic molecule covalently that is, in turn, covalently linked to an enzyme such as lactose. The method includes the steps of functionalizing a hydrophobic polymer support, covalently linking a hydrophilic molecule to said functionalized polymer support, and covalently linking an enzyme such as lactase to said hydrophilic molecule. The system and method generally relate to the field of food science and engineering and, more particularly to dairy-based food products and their production including solutions to problems associated with lactose intolerance such as product processing methods and products produced by these methods.

  • Publication number: 20130005666
    Abstract: The NF-E2-related factor 2 (Nrf2) is a key transcriptional regulator of antioxidant defense and detoxification. To directly monitor stabilization of Nrf2 we fused its Neh2 domain, responsible for the interaction with its nucleocytoplasmic regulator, Keap1, to firefly luciferase (Neh2-luciferase). It is shown herein that Neh2 domain is sufficient for recognition, ubiquitination and proteasomal degradation of Neh2-luciferase fusion protein. The novel Neh2-luc reporter system allows direct monitoring of the adaptive response to redox stress and classification of drugs based on the time-course of reporter activation. The novel reporter was used to screen a library of compounds to identify activators of Nrf2. The most robust and yet non toxic Nrf2 activators found—nordihydroguaiaretic acid, fisetin, and gedunin-induced astrocyte-dependent neuroprotection from oxidative stress via an Nrf2-dependent mechanism.

  • Patent number: 8318461
    Abstract: A process for the enzymatic hydrolysis of cellulose to produce a hydrolysis product comprising glucose from a pretreated lignocellulosic feedstock and enzymes for use in the process are provided. The process comprises hydrolyzing an aqueous slurry of a pretreated lignocellulosic feedstock with cellulase enzymes, one or more than one ?-glucosidase enzyme and a binding agent for binding the ?-glucosidase enzyme to fiber solids present in the aqueous slurry. During the hydrolysis, both the cellulase enzyme and ?-glucosidase enzyme bind to the fiber solids. The hydrolysis is performed in a solids-retaining hydrolysis reactor so that unhydrolyzed fiber solids and bound enzyme are retained in the reactor longer than the aqueous phase of the slurry.

  • Patent number: 8288143
    Abstract: A novel cold-active beta-galactosidase is enzyme specific for lactose. The enzyme is thus useful in e.g. the food industry for catalyzing at low temperatures the hydrolysis of lactose disaccharide into its constituent monosaccharides, glucose and galactose. A method produces the cold-active beta-galactosidase by recombinant DNA technology.

  • Patent number: 8278066
    Abstract: The present invention is directed to fusion proteins that can be used to assay gene transfer and expression both in vitro and in vivo. The fusion proteins contain a reporter protein, e.g. a somatostatin receptor, fused to a second protein, which may be a protein fusion tag. Alternatively, a fusion protein may be fused to a leader sequence. A leader sequence may localize an expressed protein, e.g. localize a fusion protein to the cell membrane. The invention includes nucleic acids encoding the fusion proteins and methods of assaying for gene expression.
