X-RAY DIFFRACTION . 289 The BamA-BamB chimera protein was crystallized at 16 degC by sitting drop vapor diffusion method. Initial crystallizing conditions were refined in a hanging drop in the following solution: 1.4M Ammonium sulfate, 9% 2-propanol, and 0.1M Sodium acetate pH 5.5. We used 1.5 uL of the 20mg/ml protein mixed with 1.5 uL mother liquor in a reservoir filled with 500 uL precipitant solution
