1 Heat-capacity The heat capacity of MoPrP PrP C was computed using the variance of the potential energy distribution C v = 1 k B T 2 U 2 − U 2. (1) The distribution of the potential energy in the simulations together with the computed C v for MoPrP and alanine dipeptide systems are shown in Figure S1 and S2 respectively.
