    摘要: A process for the recombinant preparation in a bacterial host of the mature form of a mammalian protein or peptide of formula X-Pro-Z, which is subject to processing by endogenous bacterial aminopeptidases is provided. In the formula X-Pro-Z, X is a single N-terminal amino acid other than proline, and Z is the remaining sequence of amino acid residues of the protein or peptide. The process comprises inserting into a cell of the bacterial host an appropriate vector containing DNA coding for Met-Y-X-Pro-Z, in which Y is a natural amino acid that is specifically cleavable in vitro from X-Pro-Z by an aminopeptidases and that imparts resistance to in vivo processing by endogenous bacterial aminopeptidases. The cell is then induced to express the expression product Met-Y-X-Pro-Z which is then treated with an appropriate aminopeptidase to cleave off Met and Y.

    摘要: The present invention relates to crystalline human farnesyl diphosphate synthase (FPPS), to the three-dimensional structure of free FPPS as well as the three-dimensional structures of FPPS in complex with substrates such as IPP (isopentenyl diphosphate) and/or with inhibitors such as Zometa® or Aredia®. Further, methods for preparing crystals of human FPPS are described. According to the invention the crystals can be used to determine the structures of FPPS homologs mutants, complexes with ligands, FPPS crystal forms and similar molecules of unknown structure. The invention further relates to the use of FPPS crystals to select new FPPS ligands, e.g. by X-ray screening and to design and/or identify inhibitors against FPPS. Furthermore, the invention relates to NMR methods for selecting and/or identifying new low molecular weight binders to FPPS, which represent new therapeutic agents.
