Figure 3
Experiments versus simulations: incomplete parameters. The AFM image (a) is compared with equilibrated snapshots of MC simulations of our fine-grained lattice model with incomplete sets of interaction effects. Panel (b) shows filaments formed when the simulation does not include lateral interactions nor excluded volume effects (i.e. isodesmic ideal polymers). Panel (c) comes from a simulation without lateral interactions (U a = 0), to be compared with the snapshot in panel (d) using the complete set of model interactions. Panel (e) corresponds to the coarser square-lattice model presented by Lan et al. [9] at the same protein coverage of a planar surface as in all the other panels.
