Specific heat CV for ℳ (green) and ℋ (red) domains of the EF-Tu and 1α proteins, respectively, calculated from OPEP-REMD simulations. The presence of multiple peaks in the CV profile is caused by the unfolding events of different secondary structure motifs as well as progressive unpacking. In a simple two-state model, the CV is expected to show a single peak at the melting temperature Tm where the populations of the folded (pf) and unfolded (pu) states are equal.
