lüll Engineering of recombinant crystallization chaperones Koide SCurr Opin Struct Biol 2009[Aug]; 19 (4): 449-57The preparation of diffraction quality crystals remains the major bottleneck in macromolecular X-ray crystallography. A crystallization chaperone is an auxiliary protein, such as fragments of monoclonal antibodies, that binds to and increases the crystallization probability of a target molecule of interest. Such chaperones reduce conformational heterogeneity, mask counterproductive surfaces while extending surfaces predisposed to forming crystal contacts, and provide phasing information. Crystallization chaperones generated using recombinant technologies have emerged as superior alternatives that increase the throughput and eliminate inherent limitations associated with antibody production by animal immunization and the hybridoma technology.|Animals[MESH]|Antibodies/metabolism[MESH]|Crystallization[MESH]|Humans[MESH]|Molecular Chaperones/chemistry/*genetics/*metabolism[MESH]|Protein Engineering/*methods[MESH]|Protein Structure, Secondary[MESH]|Recombinant Proteins/chemistry/*genetics/*metabolism[MESH] |
