pH-Dependent Interaction between C-Peptide and Phospholipid Bicelles

Figure 6

When lowering the pH to 3.2 (left panel), small structural rearrangements are induced that facilitate interaction with phospholipid bicelles. The interaction with bicelles further influences the structure. At pH 5.8, on the other hand, (right panel), no structural arrangements are seen upon addition of bicelles and the interaction is much weaker.
