Comparison of state-to-state transition rate constants of AdiC. (A–C) The reciprocals of the rate constants (1/k_i,j) plotted against the starting state i and the ending state j. The four taller columns correspond to the reciprocals of k_1,5, k_2,6, k_3,7, and k_4,8 in the absence (A) or the presence of Arg⁺ (B) or Agm²⁺ (C). The columns are color coded according to their height, namely, changing from blue toward yellow as the height increases.
