Proceedings of the National Academy of Sciences, 1997 Archaeacontain histones that have primary sequences in common with eukaryal nucleosome core histones and a three-dimensional structure that is essentially only the histone fold. Here we report the results of experiments that document that archaeal histones compact DNAin vivointo structures similar to the structure formed by the histone (H3+H4)2tetramer

Physical Review Letters, 2008 We present a statistical-mechanical model for the positioning of nucleosomes along genomic DNA molecules as a function of the strength of the binding potential and the chemical potential of the nucleosomes. We show that a significant section of the DNA is composed of two-level nucleosome switching regions where the nucleosome distribution undergoes a ...

Inter-nucleosomal potentials from nucleosomal positioning data
The European Physical Journal E, 2022 AbstractNo systematic method exists to derive inter-nucleosomal potentials between nucleosomes along a chromosome consistently across a given genome. Such potentials can yield information on nucleosomal ordering, thermal as well as mechanical properties of chromosomes.

Nucleosome Positioning, Nucleosome Spacing and the Nucleosome Code [PDF]
Journal of Biomolecular Structure and Dynamics, 2010 Nucleosome positioning has been the subject of intense study for many years. The properties of micrococcal nuclease, the enzyme central to these studies, are discussed. The various methods used to determine nucleosome positions in vitro and in vivo are reviewed critically.

Contributions of histone H3 nucleosome core surface mutations to chromatin structures, silencing and DNA repair. [PDF]
PLoS ONE, 2011 Histone H3 mutations in residues that cluster in a discrete region on the nucleosome surface around lysine 79 of H3 affect H3-K79 methylation, impair transcriptional silencing in subtelomeric chromatin, and reveal distinct contributions of histone H3 to ...

Nucleosome—nucleosome interaction in chromatin
FEBS Letters, 1979 The available data suggest that transcriptional activity of chromatin is connected with its structural changes [ 1,2]. According to the electron microscope evidence, the elementary 100 A chromatin thread can exist in two main states, i.e., in a compact state, which is characterized by tight packing of nucleosomes and in an extended state when the ...

Manipulating chromatin architecture in C. elegans
Epigenetics & Chromatin, 2022 Background Nucleosome-mediated chromatin compaction has a direct effect on the accessibility of trans-acting activators and repressors to DNA targets and serves as a primary regulatory agent of genetic expression. Understanding the nature and dynamics of
