Experimental details

Experiment

• Experiment: Method: X-RAY DIFFRACTION / Number of used crystals: 1

Sample preparation

• Crystal: Density Matthews: 2.06 ų/Da / Density % sol: 40.16 %
• Crystal grow: Temperature: 291 K / Method: vapor diffusion, sitting drop / pH: 7.5 ; Details: 2.0M ammonium sulfate, 0.2M sodium chloride, 0.1M HEPES. 1:100 (w/w) papain and GMPPNP were also added. Please note: mass spectral analysis of TEV protease digest prior to crystallization suggested that removal of the His-tag was incomplete even after 2 days. However, without TEV protease treatment no crystals were obtained using otherwise identical crystallization conditions. Also note the presence of papain in the crystallization drop., pH 7.5, vapor diffusion, sitting drop, temperature 291K
