Abstract: Methods of producing arylsulfatase A are described herein. The methods can include one or more steps of chromatography. Exemplary chromatographic steps include ion exchange chromatography, mixed mode chromatography, and hydrophobic interaction chromatography. Compositions containing and methods using arylsulfatase A produced by the methods described herein are also disclosed.
Abstract: The disclosure relates to a recombinant membrane span protein complex, comprising (1) a fusion protein, comprising a membrane span protein fused to a kinase domain, preferably a constitutive kinase and (2) a reporter construct comprising a polypeptide, interacting with the membrane span protein, fused to a reporter phosphorylation domain. The disclosure relates further to the uses of such membrane span protein complex for the detection of compounds that interact with the membrane span protein and for the screening and/or detection of inhibitors of the compound-membrane span protein interactions. In a preferred embodiment, the membrane span protein is a G protein coupled receptor (GPCR) and the method is used for the screening and/or detection of inhibitors of the ligand-receptor binding.
Abstract: A lactone hydrolase having improved activity towards ?-zearalenol is disclosed. The lactone hydrolase has a modified amino acid sequence of SEQ ID NO: 5, wherein the modification is a substitution of valine at position 167 with histidine. A method of degrading ?-zearalenol using such lactone hydrolase is also disclosed.

Abstract: A luciferase that includes an amino acid sequence in which a mutation is introduced into an amino acid sequence of a luciferase derived from Luciora kuroiwae. The luciferase catalyzes a luminescence reaction that generates luminescence having the maximum luminescent wavelength of 570 nm to 610 nm. The luminescence has an intensity at least 10 times higher than that of luminescence generated in a luminescence reaction catalyzed by a luciferase derived from Rhagophthalmus ohbai.
Abstract: The disclosure relates to a cytoplasmic protein complex comprising: (a) a first recombinant fusion protein comprising a kinase, fused to a first interaction polypeptide; and (b) a second recombinant fusion protein comprising a domain comprising a reporter phosphorylation site, whereby the domain is fused to a second interaction polypeptide. The disclosure relates further to a method to detect compound-compound-interaction using the cytoplasmic protein complex, and to cells comprising such cytoplasmic protein complex.
Abstract: The invention relates to a Bacillus anthracis (B. anthracis) in which more than one secreted protease is inactivated by genetic modification. Such a protease-deficient B. anthracis has an improved ability to produce recombinant secreted proteins compared to other bacteria, particularly other Bacillus. Improvements include production of intact (i.e., mature full-length) proteins, often at high yield. The disclosure provides a B. anthracis that comprises a genetic modification that inactivates a protease of the M4 family of metalloproteases and a genetic modification that inactivates a protease of the M6 family of metalloproteases. Also provided is a modified B. anthracis comprising such genetic modification transformed with a recombinant molecule encoding a product, as well as methods to prepare and use such B. anthracis.

Abstract: The present invention relates to a process wherein organic material derived from plant and animal material is processed to recover nutritional elements. In particular, there is provided a process for releasing nutritional elements from plant and animal material comprising the steps of treating the material with one or more enzymes to digest said material under appropriate conditions and separating the resulting liquid hydrolysate from the undigested material.
Abstract: The present invention relates to a method for suppressing or treating cancer, in particular to a method for suppressing or treating one or more of colorectal cancer, breast cancer, prostate cancer and/or lung cancer. The therapy employs use of a non-cytotoxic protease, which is targeted to a growth hormone-secreting cell such as to a pituitary cell. When so delivered, the protease is internalized and inhibits secretion/transmission of growth hormone from said cell. The present invention also relates to polypeptides and nucleic acids for use in said methods.

Abstract: The invention relates to a new family of proteolytic enxymes having the ability to hydrolize at a pH between 3 and 8 gluten olygopeptides which are resistant to cleavage by gastric and pancreatic enzymes and whose presence in the intestinal lumen results in toxic effects. The enzymes have been identified as endopeptidases of the S8/S53 family and are produced by an Actinoallomurus strain. The object of the invention includes also methods for producing enzymes composition comprising the endopeptidases by cultivation of native Actinoallomurus strains, mutants thereof, or recombinant host cells comprising nucleic acids codifying for the endopeptidases. Said nucleic acids constitute a further object of the invention.

Abstract: Problem to be Solved An object of the present invention is to provide a separase sensor for visualizing separase activity in a living cell. Another object is to develop a function analysis system of cell division using the separase sensor and further obtain a simple screening method for an anticancer agent. Solution The separase sensor of the present invention has two types of fluorescent proteins different in fluorescence wavelength at both ends of an amino acid sequence containing a separase cleavage site and a localization-targeting sequence targeting to a specific site within a cell. Since timing of activating separase and location of separase in a cell can be specified by use of the sensor, cell division can be analyzed and an anticancer agent can be screened.
