Figure 4
Calculated anomalous differences. Calculated d′′/sig(d′′) from refined structures as a function of resolution. The graph shows the signal to noise from the anomalous differences. In the red part of the graph the anomalous signal is considered to be nonexistent. The d′′/sig(d′′) calculated from the final structure, from a structure with cysteine side chains flipped by 180° and from a structure with S atoms from disulfide bonds moved 10 Å away from each other are coloured blue, green and red, respectively. |
