The present invention relates to a secretagogue compound derived from oxalate degrading bacteria, for use in the treatment of an oxalate related disease and/or oxalate related imbalance in a subject, wherein the administration of the secretagogue results in a reduction of urinary oxalate and/or plasma oxalate in the subject. The invention further relates to a pharmaceutical composition comprising such a secretagogue compound, a method for treating a subject suffering from an oxalate related disease, and to a method for preparing a secretagogue.

The present invention concerns in general novel fusion proteins comprising a membrane-transferring moiety and an enzymatic moiety. The present invention further concerns a method of treating disease using said fusion proteins.

Provided herein are host cells or host cellular expression systems that express a membrane protein. Also, methods are provided that use such host cells or host cellular expression systems to produce higher amounts of the membrane proteins. Further, the cells or cellular systems can be used as tools for the functional characterization of membrane proteins, as well as for screening and drug discovery efforts targeting membrane proteins.

The present invention relates to cofactor regeneration systems, components and uses thereof and methods for generating and regenerating cofactors. The cofactor regeneration system comprises a first electron transfer component selected from a polypeptide comprising a NADH:acceptor oxido-reductase or NADPH:acceptor oxido-reductase, a second electron transfer component selected from a hydrogenase moiety and/or non-biological nanoparticles and an electronically conducting surface. The first and second electron transfer components are immobilised on the electrically conducting surface, and the first and second electron transfer components do not occur together in nature as an enzyme complex.

Provided is a process for the preparation of L-methionine in an enzymatic reaction utilizing dimethyl disulfide (DMDS) a precursor of L-methionine, and an organic reducing compound. In the process, methyl mercaptan can be formed by the enzymatic hydrogenolysis of the DMDS.

Codon optimized nucleic acid sequences for the long form and short form of RdCVF are provided, as well as recombinant viral vectors, such as AAV, expression cassettes, proviral plasmids or other plasmids containing the codon optimized sequences. Recombinant vectors are provided that express the codon optimized RdCVFL and RdCVF individually, or express two copies of a codon optimized RdCVF or RdCVFL nucleic acid sequence, or both RdCVFL and RdCVF in a single vector or virus. Compositions containing these codon optimized sequences are useful in methods for treating, retarding or halting certain blinding diseases resulting from the absence or inappropriate expression of RdCVF and RdCVFL.

The present invention is directed to the cells, compositions and methods for the production of recombinant protein, wherein an f-met group on the 5-terminus is enzymatically removed. In particular, the invention is directed to a production process for obtaining high levels of soluble recombinant CRM.sub.197 protein from E. coli. Cells preferably contain one or more mutations of disulfide reductase genes, so that disulfide reductase activity is reduced. The invention also relates to purification method for CRM.sub.197 as well as characterization of properly folded CRM.sub.197 protein.

The invention in suitable embodiments is directed to purified clathrin protein therapeutics. In one aspect, one or more purified clathrin protein therapeutic, formed in whole or in part from isolated, synthetic and or recombinant amino acid residues comprising in whole or in part one or more clathrin heavy chain protein and isoforms thereof, forms one or more type of therapeutic agent for treating psychiatric disorders.

The invention in suitable embodiments is directed to purified clathrin protein therapeutics. In one aspect, one or more purified clathrin protein therapeutic, formed in whole or in part from isolated, synthetic and or recombinant amino acid residues comprising in whole or in part one or more clathrin heavy chain protein and isoforms thereof, forms one or more type of therapeutic agent for treating neuropsychiatric diseases and disorders.

The present invention provides methods for producing disulfide oxidoreductase A (DsbA) and disulfide oxidoreductase C (DsbC) polypeptides at very high levels of purity. Also provided are ultrapure DsbA and DsbC and methods of using same, e.g., for use in immunoassays to show removal of DsbA and DsbC from biologics produced in bacteria.
