Figure 6.
The free energy landscape as determined by 2D WHAM analysis of the umbrella sampling data on NEB determined structural evolution images along the loop open-closure conformational exchange pathway. ΔRMSD is the X coordinate and Psi356 is the Y coordinate. The two endpoint starting structures were prepared from PDBID:3U96 (Y357F mutant) according to the procedure described in Methods section. The side bar shows the color coded energy levels (kcal/mol).
