Crystal structure of E. coli Bacterioferritin (BFR) obtained after soaking APO-BFR crystals for 2.5 minutes in FE2+ (2.5M FE(II)-BFR)
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 5 298 1.8 M AMMONIUM SULFATE, 0.1 M TRI- SODIUM CITRATE PH 5.0. SUBSEQUENTLY, APO-BFR CRYSTALS WERE SOAKED IN A CRYOPROTECTANCT CONTAINING FE2+ AND BUFFERED USING MOPS PH 7 IN PLACE OF CITRATE PH 5. EXPOSURE TO IRON WAS LIMITED TO 2.5 MINUTES BEFORE FLASH FREEZING IN LIQUID NITROGEN. SEE PAPER FOR FULL DETAILS., VAPOR DIFFUSION, SITTING DROP, TEMPERATURE 298K, pH 5.00
