Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 2HUW
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 8.5 298 Ligand in lyophilized powder form was dissolved in a 7.2 mg/mL solution of Grb2 SH2 in water such to give a protein/ligand molar ratio of 1:1.7. 4 uL of this solution was mixed with 3 uL of 12% v/v glycerol, 1.5 M ammonium sulfate, 0.1 M TRIS, pH 8.5 to create the hanging drop, which yielded crystals of the protein-ligand complex after 8 weeks, VAPOR DIFFUSION, HANGING DROP, temperature 298K
