TY - JOUR ID - Yu:2003 L3 - citeulike-article-id:5154728 N2 - The normal modes of myoglobin, their lifetimes, the speed of sound, and mean free path are calculated to determine the coefficient of thermal conductivity and thermal diffusivity for the protein. A propensity is found for frequency differences of pairs of normal modes localized to nearby regions of the protein to be several hundred cm-1. As a result, the anharmonic decay rate of higher frequency, localized normal modes, calculated by perturbation theory, is typically nearly independent of temperature, consistent with results of pumpprobe studies on myoglobin. The thermal diffusivity of myoglobin at 300 K is calculated to be 14 A2 ps-1, the same as the value for water. The thermal conductivity at 300 K is found to be 2.0 mW cm-1 K-1, about one-third the value for water.
