Figure 4.
2D free energy surface and reaction strings for the complete catalytic reaction with a protonated Asp132, obtained by projection onto coordinates Qe=ET probing bond formation and breaking, and Qp=(PT1a+PT1b)/2+PT2 probing PT steps. The black curve shows the initial string; the blue and purple curves show the converged strings for the entire reaction and for the final step, respectively. The inset shows a schematic of the active site coordination.
