Changes in thermodynamic parameters between first and second LC8 binding events (ΔΔG°, grey diamonds; ΔΔH°, black circles; and Δ-TΔS°, white squares). Differences in association parameters at different temperatures between LC8 binding to monovalent apo-ICLL and LC8 binding to bivalent ICLL/LC8 (left), and between LC8 binding to monovalent SwaMONOMER and LC8 binding to bivalent SwaDIMER (right). The absence of temperature dependence (ΔΔCp of zero) shows that binding enhancement (ΔΔG°) is not due to enthalpic change (ΔΔH° of zero) but due to entropic change (Δ-TΔS° of same value as ΔΔG°).
