(a) C^α chemical shift perturbations between free CFL2 and CFL2/F-actin. Residues present in dREDOR experiments of CFL2/F-actin are shown with blue bars above the plot and labeled in blue. Chemical shifts of free CFL2 were determined by solution NMR experiments. Chemical shifts of CFL2/F-actin complexes were determined by MAS NMR experiments. (b) The residues constituting the corresponding chemical shift perturbations are mapped onto the CFL1 structure (PDB 1Q8G). Chemical shift perturbations between 2–4 ppm are shown in yellow and chemical shift perturbations above 4 ppm are shown in red.
