Abstract. All cells employ architectural proteins to confine and organize their chromosomes, and to prevent the otherwise thermodynamically favored collapse of concentrated DNA into compact structures. To accomplish this, prokaryotes have evolved a variety of phylogenetically unrelated, small, basic, sequence-independent DNA-binding proteins that include histones in Euryarchaeota, and members of the HU family in many Bacteria. In contrast, virtually all Eukarya employ histones, and recently a… Expand

Archaeal Histone Contributions to the Origin of Eukaryotes.
TLDR
The eukaryotic lineage arose from bacterial and archaeal cells that underwent a symbiotic merger that contributed genes, metabolic energy, and the building blocks of the endomembrane system. Expand
Structure and function of archaeal histones
TLDR
The amino acid determinants of hypernucleosome formation are discussed and differences with the canonical eukaryotic octamer are highlighted and possibilities of involvement of histones in archaeal transcription regulation are discussed. Expand
[10] Archaeal histones and nucleosomes
TLDR
This chapter provides protocols for the purification of archaeal histones and nucleosomes, and procedures for assays of DNA binding and Archaeal nucleosome positioning. Expand
Structure and functional relationships of archaeal and eukaryal histones and nucleosomes
TLDR
A comparison of the properties of both nucleosomes in terms of DNA packaging and the accessibility of the packaged DNA for transcription is compared. Expand
The Major Architects of Chromatin: Architectural Proteins in Bacteria, Archaea and Eukaryotes
TLDR
It is concluded that the underlying mechanisms that shape and remodel genomes are remarkably similar among bacteria, archaea and eukaryotes. Expand
Phylogenomics of the nucleosome
TLDR
Diversification of histone variants and 'deviants' contradicts the perception of histones as monotonous members of multigene families that indiscriminately package and compact the genome. Expand
Prokaryotic and eukaryotic chromosomes: what's the difference?

  • Biology, Medicine
  • BioEssays : news and reviews in molecular, cellular and developmental biology
  • 2000
TLDR
It is suggested that the criterion of nucleosome-based packaging of chromosomal DNA may be more useful than the prokaryote/eukaryote dichotomy for inferring the broadest phylogenetic relationships among organisms. Expand
Long-Term Evolution of Histone Families: Old Notions and New Insights into Their Mechanisms of Diversification Across Eukaryotes
TLDR
The present chapter is aimed at providing a comprehensive review of the most recent information on the origin of eukaryotic histone multigene families, paying particular attention to the structural and functional constraints acting on histones and their relevance for the progressive diversification of histone variants during evolution. Expand
Molecular components of the archaeal nucleosome.
TLDR
Through a combination of sequence comparisons, 3D structural studies, site-directed mutagenesis and assays for DNA binding, most of the individual residues in the histone fold of the representative archaeal histone rHMfB are assigned, and these define DNA structures that positionarchaeal nucleosome assembly. Expand
Archaeal chromatin proteins: different structures but common function?
TLDR
Of the numerous chromatin proteins that have been described in Archaea, only two--histones and Alba homologs--are present in all archaeal phyla and although their structures and complexes with DNA have no similarities, their functions probably overlap as mutants that lack single Chromatin proteins are viable.

Evidence for an early prokaryotic origin of histones H2A and H4 prior to the emergence of eukaryotes.
TLDR
Sequence analyses indicate that the N-terminal repeat is most closely related to eukaryotic H2A and H4 histones, whereas the C-Terminal repeat resembles that found in prokaryotic histones which implies an early divergence within the histone gene family prior to the emergence of eukARYotes. Expand

Archaeal nucleosomes.
TLDR
Results of experiments are reported that document that archaeal histones compact DNA in vivo into structures similar to the structure formed by the histone (H3+H4)2 tetramer at the center of the eukaryal nucleosome. Expand
Archaeal Histones, Nucleosomes, and Transcription Initiation
TLDR
Although Archaea lack a nuclear, they do contain histones that compact DNA ally bulkier, and space and interaction constraints im-into nucleosome-related structures, and archaeal RNA posed by these different R groups presumably direct polymerases have the multisubunit complexity of eucar-the correct eucaryal histone heterodimerization and pre-yal RNA polymerases.

Physiologically important stabilization of DNA by a prokaryotic histone-like protein.
TLDR
It is suggested that the physiological function of the thermophilic mycoplasma Thermoplasma acidophilum is to prevent complete separation of the DNA strands during brief exposures of the organism to denaturing conditions, and thus to facilitate rapid renaturation when normal environmental conditions return.

Archaebacterial histone-like protein MC1 can exhibit a sequence-specific binding to DNA.
TLDR
The binding of MC1 protein to the region preceding the strongly expressed genes encoding methyl coenzyme reductase in a closely related micro-organism has been investigated and it is shown that the DNA bends upon MC1 binding. Expand
DNA binding by the archaeal histone HMf results in positive supercoiling.
TLDR
It is shown here that HMf binding increases the helical periodicity of DNA molecules to approximately 11 base pairs (bp) per turn and that DNA molecules in these nucleosome-like structures are constrained in positive toroidal supercoils. Expand
HMf, a histone-related protein from the hyperthermophilic archaeon Methanothermus fervidus, binds preferentially to DNA containing phased tracts of adenines
HMf, a histone-related protein from Methanothermus fervidus, was found to bind preferentially to a DNA that is intrinsically bent as a result of the presence of phased oligo(dA) tracts. The… Expand
The hyperthermophile chromosomal protein Sac7d sharply kinks DNA
TLDR
The crystal structure of Sac7d in complex with two DNA sequences to high resolution is solved and it is revealed thatSac7d binds in the minor groove, causing a sharp kinking of the DNA helix that is more marked than that induced by any sequence-specific DNA-binding proteins. Expand
