Contact map constructed from the conformation ensemble simulated by the present Gō model at around the transition state of folding. (a) 2LHC, (b) 2LHD, (c) 2LHG, and (d) 2LHE. A darker spot indicates the high occurrence of conformations with a contact corresponding to the spot. The numbers, for example "80-100", on the right side of the figure are the number of conformations during a simulation near the transition state. A black bar denotes the location of an α helix, and a black arrow indicates the location of a β strand.
