Figure 6. EPR linewidths show that the N-terminal amyloid core of Orb2A88 is static whereas the rest of the protein becomes increasingly dynamic towards the C-terminus.

Inverse central linewidths of 10% spin labeled samples. The smaller the inverse EPR linewidth, the less dynamic the corresponding spin label. The data confirm that the most static domain of Orb2A88 is within the N-terminal region and that the C-terminus is highly dynamic.
