TraN crystallization and data collection. (a) A representative TraN crystal which grew very compactly to a maximal size of about 400 µm. The crystal was grown using the microbatch method at 293 K and using paraffin oil only to seal the plate. The protein drop ratio was 50% with a protein stock concentration of 4.6 mg ml−1. The drop size was 1 µl with the crystallization buffer Index condition No. 72: 0.2 M NaCl, 0.1 M HEPES pH 7.5, 25%(w/v) PEG 3350. (b) Diffraction pattern of a native TraN crystal obtained using synchrotron radiation on beamline X06DA, SLS, Villigen, Switzerland; resolution rings have been added. The picture was generated using ADXV (A. Arvai). Inset, detail of the diffraction shown in (b). |
