X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	5.4	295	A stock crystallization solution was prepared by adding T. thermophilus RNAP holoenzyme (10 mg/ml) in 20 mm TRIS-HCl, ph 7.7, 100 mm NaCl, and 1% glycerol to an equal volume of 33 mm magnesium formate containing 40 m ZnCl2. This solution was equilibrated against 35 mm magnesium formate and 30 mm sodium citrate, ph 5.4, vapor diffusion, hanging drop, temperature 295K, VAPOR DIFFUSION, HANGING DROP
