Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.5	293	The best crystals of full-length native and selenomethionine-derivatized PorU were obtained at 20 degrees in drops with 1 microL of protein solution (at 5-10 mg per mL in 20 mM Tris-HCl, 150 mM NaCl, pH 7.5) and 1 microL of reservoir solution (100 mM HEPES, 200 mM calcium chloride, 28-32 per cent v/v PEG600, pH 7.5). Crystals were cryoprotected by rapid passage through drops containing increasing amounts of glycerol (5-to-20 per cent v/v).
