Novel histones and histone variant families in prokaryotes

S Schwab, Y Hu, B van Erp, MKM Cajili, MD Hartmann… - bioRxiv, 2023 - biorxiv.org
Histones are important chromatin-organising proteins in eukaryotes and archaea. They form
superhelical structures around which DNA is wrapped. Recent studies have shown that …

Archaeal histone selection of nucleosome positioning sequences and the procaryotic origin of histone-dependent genome evolution

KA Bailey, SL Pereira, J Widom, JN Reeve - Journal of molecular biology, 2000 - Elsevier
Archaeal histones and the eucaryal (eucaryotic) nucleosome core histones have almost
identical histone folds. Here, we show that DNA molecules selectively incorporated by …

The hypersaline archaeal histones HpyA and HstA are DNA binding proteins that defy categorization according to commonly used functional criteria

S Sakrikar, RK Hackley, M Martinez-Pastor, CL Darnell… - Mbio, 2023 - Am Soc Microbiol
Histone proteins are found across diverse lineages of Archaea, many of which package
DNA and form chromatin. However, previous research has led to the hypothesis that the …

[HTML][HTML] Archaeal histone contributions to the origin of eukaryotes

CF Brunk, WF Martin - Trends in microbiology, 2019 - cell.com
The eukaryotic lineage arose from bacterial and archaeal cells that underwent a symbiotic
merger. At the origin of the eukaryote lineage, the bacterial partner contributed genes …

Long-term evolution of histone families: old notions and new insights into their mechanisms of diversification across eukaryotes

JM Eirín-López, R González-Romero… - … : concept, modeling, and …, 2009 - Springer
In eukaryotes and some archaebacteria, DNA is found associated with histones in a
nucleoprotein complex called chromatin, which allows for a high extent of compaction of …

[HTML][HTML] Growth temperature and chromatinization in archaea

A Hocher, G Borrel, K Fadhlaoui, JF Brugère… - Nature …, 2022 - nature.com
DNA in cells is associated with proteins that constrain its structure and affect DNA-templated
processes including transcription and replication. HU and histones are the main constituents …

[HTML][HTML] Archaeal histone-based chromatin structures regulate transcription elongation rates

BR Wenck, RL Vickerman, BW Burkhart… - Communications …, 2024 - nature.com
Many archaea encode and express histone proteins to compact their genomes. Archaeal
and eukaryotic histones share a near-identical fold that permits DNA wrapping through …

An alternative beads‐on‐a‐string chromatin architecture in Thermococcus kodakarensis

H Maruyama, JC Harwood, KM Moore… - EMBO …, 2013 - embopress.org
We have applied chromatin sequencing technology to the euryarchaeon Thermococcus
kodakarensis, which is known to possess histone‐like proteins. We detect positioned …

Growth phase‐dependent expression and degradation of histones in the thermophilic archaeon Thermococcus zilligii

ME Dinger, GJ Baillie, DR Musgrave - Molecular microbiology, 2000 - Wiley Online Library
HTz is a member of the archaeal histone family. The archaeal histones have primary
sequences and structural similarity to the eukaryal histone fold domain, and are thought to …

[HTML][HTML] DNA-bridging by an archaeal histone variant via a unique tetramerisation interface

S Ofer, F Blombach, AM Erkelens, D Barker… - Communications …, 2023 - nature.com
In eukaryotes, histone paralogues form obligate heterodimers such as H3/H4 and H2A/H2B
that assemble into octameric nucleosome particles. Archaeal histones are dimeric and …
