MOTIVATION We describe a Brownian dynamics model for the folding of the chromatin fiber based on the model of Woodcock et al. (Proc Natl Acad Sci USA, 90, 9021-9025, 1993). The model takes into account the elastic properties of the DNA as well as the electrostatic interaction and nucleosomal excluded-volume interaction. The solvent is described as a viscous(More)
The hydration properties of a protein are important determinants of its structure and function. Here, modular neural networks are employed to predict ordered hydration sites using protein sequence information. First, secondary structure and solvent accessibility are predicted from sequence with two separate neural networks. These predictions are used as(More)
Extended planar hydrophobic surfaces, such as are found in the side chains of the amino acids histidine, phenylalanine, tyrosine, and tryptophan, exhibit an affinity for the weakly hydrated faces of glucopyranose. In addition, molecular species such as these, including indole, caffeine, and imidazole, exhibit a weak tendency to pair together by hydrophobic(More)
