PEX5 - PEX14 interaction by isothermal titration calorimetry. ITC experiments were performed as triplicates. (A) Titration of 50 μM PEX5 in aqueous buffer into a 30 μM aqueous solution of PEX14. (B) The same experiment in the presence of 44 μM bicelle corresponding to full saturation of PEX5 and PEX14 with 0.9- fold and 1.5- fold molar excess, respectively. (C) The titration experiments in membrane-like environment show reduced binding enthalpies ΔH and entropic contribution –TΔS and slightly reduced affinity compared to experiments in aqueous solution.
