Structure of the Arabidopsis thaliana SOS3 complexed with Calcium(II) ion
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION 4.8 PRIOR TO CRYSTALLIZATION THE PROTEIN WAS PREINCUBATED WITH 3.8 MM CACL2 TO REACH A FINAL PROTEIN CONCENTRATION OF 10 MG/ML AND A PRTEIN:METAL ION RATIO 1:10. CRYSTALLIZATION EXPERIMENTS WERE CARRIED OUT AT ROOM TEMPERATURE. CRYSTALS WERE GROWN USING VAPOUR DIFFUSION TECHNIQUES FROM DROPS CONTAINING SOS3-CA, RESERVOIR SOLUTIONS (24%(W/V) METHYL-PENTANEDIOL, 18%(W/V) POLYETHYLENE GLYCOL 4000 AND 0.1 NA-CITRATE PH 4.8) AND NAI 1M IN A RATIO 2:1:0.75
