| 1 | VAPOR DIFFUSION, SITTING DROP | 7.5 | 291 | 0.4 M magnesium chloride, 0.1 M HEPES buffer. Full length protein consisting of 214 original residues was used for crystallization. The obtained crystals contain only C-terminal domain of the protein, probably, due to proteolysis of the protein in crystallization conditions. , pH 7.5, VAPOR DIFFUSION, SITTING DROP, temperature 291K |
