We report on molecular dynamics simulations of the helix-coil transition of a polypeptide. The simulated transition was two-state-like and similar to the solid-liquid-like transition that has been observed in computer simulations of an atomic cluster. At the transition temperature, the polypeptide chain fluctuated between a helical and a random-coil state, and we observed 1/f fluctuation through potential-energy fluctuations. The origin of the observed 1/f fluctuation is discussed, considering the underlying potential-energy landscape.
