Viral histones: pickpocket’s prize or primordial progenitor?
TL;DR: Viral histones can be highly similar to eukaryotic histones in primary sequence and may occur as conjoined histone doublets, triplets, or quadruplets as discussed by the authors .

Small Prokaryotic DNA-Binding Proteins Protect Genome Integrity throughout the Life Cycle
Katja Molan,Darja Žgur Bertok +1 more
TL;DR: This work has shown that single-stranded binding proteins prevent the formation of secondary structures but also protect the hypersensitive ssDNA against chemical and nuclease degradation in the extremophile Deinococcus radiodurans.

TL;DR: In this article, the effect of single amino acid substitutions in archaeal histones that block formation of tightly packed chromatin structures have profound effects on cellular fitness, but the underlying gene expression changes resultant from an altered chromatin landscape have not been resolved.

Histone variants in archaea - An undiscovered country.
TL;DR: A review of histone variants in archaea at the level of structure, regulation, and evolution can be found in this article , where the authors sketch a preliminary roadmap for further exploration of this country.

Crystal structure of the nucleosome core particle at 2.8 Å resolution
TL;DR: The X-ray crystal structure of the nucleosome core particle of chromatin shows in atomic detail how the histone protein octamer is assembled and how 146 base pairs of DNA are organized into a superhelix around it.

Spheroid Chromatin Units (ν Bodies)
Ada L. Olins,Donald E. Olins +1 more
TL;DR: Linear arrays of spherical chromatin particles about 70 angstroms in diameter have been observed in preparations of isolated eukaryotic nuclei swollen in water, centrifuged onto carbon films, and positively or negatively stained.
Journal ArticleDOI
X-ray structure of a tetranucleosome and its implications for the chromatin fibre
TL;DR: The crystal structure of an oligonucleosome (a compact tetranucleosom) at 9 Å resolution is reported, solved by molecular replacement using the nucleosome core structure, and suggests that the interfaces between nucleosomes along a single helix start are polymorphic.
Journal ArticleDOI
Bacterial nucleoid-associated proteins, nucleoid structure and gene expression
TL;DR: NAP biology is considered from the standpoints of both gene regulation and nucleoid structure to show that nucleoid-associated proteins (NAPs) and transcription contribute in combination to the dynamic nature of nucleoids structure.
Journal ArticleDOI
Mechanisms of action and regulation of ATP-dependent chromatin-remodelling complexes
TL;DR: The 'hourglass' model of remodeller function is proposed, in which each remodeller subfamily utilizes diverse specialized proteins and protein domains to assist in nucleosomes targeting or to differentially detect nucleosome epitopes.
