1 | VAPOR DIFFUSION, SITTING DROP | 277 | The HODM-heme subunit was crystallised at 3 mg ml-1 in 50 mM KPi, 100 mM KCl, pH 7.5. Initial crystallisation conditions were identified using the JCSG+ matrix screen (Molecular dimensions). Crystals suitable for diffraction experiments were obtained by sitting drop vapour diffusion at 277 K in 400 nL drops containing equal volumes of protein and a solution containing 30% PEG 2K MME and 0.1 M potassium thiocyanate. |
