Resumo
The composition of lysozyme solutions in D2O under conditions favorable for the formation of tetragonal crystals has been investigated at different protein concentrations by small-angle X-ray scattering using the synchrotron radiation. In addition to lysozyme monomers, dimeric and octameric species are found in the crystallization solutions; the octamer content increases with an increase in the protein concentration. A comparison of the data with those obtained under similar conditions but with H2O used as a solvent has shown that the replacement of light water with heavy one leads to increase of octamer volume fraction in solution.
