Webthe lysozyme,23 myoglobin,24 and ferricytochrome c2' crystals contain 33.5, 40, and 55% solvent of crystallization respectively. (Since the density of the solvent of crystallization is approximately equal to the mean protein density in these cases, percentages by weight and volume are nearly equivalent.) These data demonstrate the feasibility ... WebApr 28, 2016 · If by dehydration, one can lower their global solvent content maintaining the protein molecules order (Fig. 6.1b) (higher protein to solvent ratio) could lead to an improved diffracting power. Changes in solvent content need to be accompanied by small local rearrangements in the crystal contacts and/or flexible areas, therefore diffraction …
