Comparison of SAXS data I(q) vs. q obtained from (blue) inactive SVs and (orange) active SVs upon the addition of 1 mM ATP and 10 mM K-glutamate. For the control experiment, 10 mM K-glutamate, without ATP, was added to the SV suspension (green curve). The inset shows the SAXS data set for lower q-values, where main differences can be observed between the different SAXS signals
