Overlap of nine final structures of native SMTP in water only (water not shown) displayed by cartoon. The starting conformation indicated by green was always the same, and the final structures were observed after 50 ns of trajectories of various ionic strength: (a) 0.01 M; (b) 0.05 M; (c) 0.7 M. The colors code the temperature of the system in given ionic strength: 293 K, blue; 310 K, orange; 310 K, yellow. Peptide ends are annotated.
