Fig. 4.
Ribbon diagrams showing the possible salt-bridge forming residues in ARPC2 (cyan) and mother filament subunits M8 (transparent, left) and M6 (transparent, right) that were identified during MD simulations. Panel A shows the ARPC2 clamp spanning M6/M8 dimer. Panel B shows a close up of the possible salt-bridge forming residues with subunits M8 (left) and M6 (right). Side chains of residues forming salt bridges are labeled and drawn with licorice representation.
