| 摘要 |
The invention relates to 3-D structures of a polypeptide, whereby, in the 3- D structure, the polypeptide contains at least one amino acid sequence of a TP R- structure motif from a Hop protein, or a derivative thereof. The invention further relates to crystals, comprising at least one polypeptide in their asymmetric unit and, optionally, at least one further compound, whereby the polypeptide adopts the above 3D-structure in the crystal. Furthermore, metho ds for the production of such crystals and compounds, having the property of binding, as ligands, to structural regions of a Hop protein are disclosed. Additionally, a method for the identification of inhibitors is disclosed, whereby ligands with inhibitor functions for the interaction of a Hop protei n with at least one chaperone protein are obtained. Such inhibitors are useful for the treatment of tumour disease states, immunosupression, GVDH, or the treatment of viral infections.
