Figure 3
RIDL isomorphous difference maps comparing thaumatin data sets at the exemplar disulfide bond Cys134–Cys145. Rows and columns are sorted in order of average dose in the exposed region (ADER), with lowest doses at the top and left-hand sides. If site-specific damage is occurring and is a function of ADER, the largest features should appear towards the bottom left of the figure where the largest differences in dose occur. The top inset compares Dloss (in e Å−3) at Cys134–Cys145 between pairs of data sets, as calculated by RIDL, as a function of the difference in ADER dose between each data set. The lower inset shows the S—S bond length as a function of ADER dose; this is shown for all disulfide bonds in Supplementary Fig. S6. An analogous figure with columns and rows sorted by beam power rather than dose is given in Supplementary Fig. S8. All difference maps are contoured at 3σ.
