Figure 3
Increase in volume of the two crystal forms of AspRS-70 after optimization of crystallization conditions. (a) Best tetragonal bipyramid obtained in the sparse matrix and (b) crystals grown under condition A3 of the phase diagram (protein at 10 mg ml−1 in 2.0 M ammonium sulfate). (c) Needle-like crystals obtained at pH 7.8 and (d) trigonal prism after refinement (protein at 3 mg ml−1 in 2.6 M ammonium sulfate and 100 mM Tris–HCl at pH 7.8). All crystals are shown at the same magnification.
