Stress-induced extension of ¹Fn1²Fn1 (purple) in the presence of the FnBP peptide (red). Snapshots of the FnBP-¹Fn1²Fn1 complex are taken at a t = 0 ns, b t = 3 ns, c t = 7 ns, and d t = 10 ns from one of the four pulling simulations; the extensions of the individual modules and the linker (defined in Fig. 2) are shown in e, along with the corresponding applied force, as functions of time
