Typical force–extension curves of heteropolyprotein (A–D) (GB1-I27-DEFG-I32)4, (GB1- I27-CFG-I32)4, (GB1- I32-CFG-I27)4, and (GB1-I27-FG-I32)4. The force–extension curves of these heteropolyproteins are characterized by long featureless spacers followed by the unfolding events of GB1 domains, which corresponds to the stretching of hybrid Ig domains that unfold at low force (below our detection limit). Dotted lines are WLC fits to the experimental data.
