Figure 6: Force-dependent change in the transition state structure.

The extent of structure formation in the unfolding transition states of src SH3 for (a) Pathway B, (b) Pathway S1 and (c) Pathway S2. The unfolding φ-values are represented as a heat map, ranging from φ=0 (completely structured, blue) to φ=1 (completely unstructured, red).
