| - | ==Overview==
| + | |
| - | One reason for introducing a gel in the crystallization medium of proteins, is its ability to reduce convection in solution. This can lead to better, nucleation and growth conditions, and to crystals having enhanced, diffraction properties. We report here the X-ray characterization at room, temperature of high-quality crystals of the intensely sweet thaumatin, prepared in a sodium tartrate solution gelified with 0.15% (m/v) agarose., Using a synchrotron radiation, these crystals diffracted to a previously, unachieved resolution. A diffraction dataset was collected from four, crystals at a resolution of 1.2 A with a R(sym) of 3.6% and a completeness, of 99%. Refinement was carried out to a final crystallographic R-factor of, 12.0%. The quality of the electron density map allowed for the observation, of fine structural details in the protein and its solvation shell., Crystallization in gel might be used more generally to improve the quality, of macromolecular crystals. Advantages provided by the gelified medium in, the frame of structural studies are emphasized.
