Our physics-based method is used with a template from a high-resolution crystal structure (25) to predict the nucleosome formation energy, En ? El (where En is the energy of the particular sequence on DNA that is bent to fit the nucleosome and El is the energy of the same sequence on ideally straight B-DNA, termed “linear DNA”). El is used as reference energy to eliminate the dependence on trivial effects such as the number of hydrogen bonds made between the two strands. Fig. 2 compares our predicted energy with the in vitro experimental occupancy for sequence positions from 187,000 to 207,000 in yeast chromosome 14 (26, 27); it shows clear negative correlation between the two data sets: The in vitro nucleosome occupancy is higher at the sequence positions where the nucleosome formation energy is lower. Position-dependent correlations (Fig. 2A) show that the correlation is generally uniform along the sequence although there are regions with high correlation (195,000–199,000) and others with low correlation (187,000–191,000). Fig. 2B depicts the in vitro experimental nucleosome occupancy and computed nucleosome formation energies. The overall correlation between the experimental and modeled data are ?0.612. Fig. S2 shows the ab initio nucleosome occupancy profiles obtained when energies are converted to probabilities of occupancy using the Boltzmann formula (SI Materials and Me personallythods). (mais…)
