IDMethodpHTemperatureDetails
1VAPOR DIFFUSION, SITTING DROP8.5289TRF1-TRFH and TERB1-TBM were mixed in a 1:5 molar ratio and crystal screens set up using 0.3 microliter protein solution and 0.3 microliter reservoir solution in a sitting drop format. Diffracting crystals were obtained in 0.1 M Tris-Cl (pH 8.5) and 30% PEG 300. Crystals were cryoprotected in the crystallization solution plus 10% PEG 400 and harvested in liquid nitrogen.
