Figure 5
Harker sections (w = 0) of the anomalous difference Patterson maps from recombinant sperm-whale myoglobin. Images were processed with either (a) the HKL suite or (b) the d*TREK suite and the resulting reflections were processed with the CCP4 (Collaborative Computational Project, Number 4, 1994) package. Contours start at 4σ and are at intervals of 8σ, where σ is the standard deviation of the grid values in the complete unit cell. The Rmerge for the HKL-processed data is 4.7%; for the d*TREK-processed data, Rmerge is 4.9%. |
