Archaeal Phylogeny Based on Ribosomal Proteins [PDF]

Molecular Biology and Evolution, 2002
Until recently, phylogenetic analyses of Archaea have mainly been based on ribosomal RNA (rRNA) sequence comparisons, leading to the distinction of the two major archaeal phyla: the Euryarchaeota and the Crenarchaeota. Here, thanks to the recent sequencing of several archaeal genomes, we have constructed a phylogeny based on the fusion of the sequences

Remote Homology Detection Identifies a Eukaryotic RPA DBD-C-like DNA Binding Domain as a Conserved Feature of Archaeal Rpa1-Like Proteins

Frontiers in Molecular Biosciences, 2021
The eukaryotic single-stranded DNA binding factor replication protein A (RPA) is essential for DNA replication, repair and recombination. RPA is a heterotrimer containing six related OB folds and a winged helix-turn-helix (wH) domain.

Archaeal chromatin proteins

Science China Life Sciences, 2012
Archaea, along with Bacteria and Eukarya, are the three domains of life. In all living cells, chromatin proteins serve a crucial role in maintaining the integrity of the structure and function of the genome. An array of small, abundant and basic DNA-binding proteins, considered candidates for chromatin proteins, has been isolated from the Euryarchaeota

Different Proteins Mediate Step-Wise Chromosome Architectures in Thermoplasma acidophilum and Pyrobaculum calidifontis

Frontiers in Microbiology, 2020
Archaeal species encode a variety of distinct lineage-specific chromosomal proteins. We have previously shown that in Thermococcus kodakarensis, histone, Alba, and TrmBL2 play distinct roles in chromosome organization.

The Archaeome’s Role in Colorectal Cancer: Unveiling the DPANN Group and Investigating Archaeal Functional Signatures

Microorganisms, 2023
Background and Aims: Gut microbial imbalances are linked to colorectal cancer (CRC), but archaea’s role remains underexplored. Here, using previously published metagenomic data from different populations including Austria, Germany, Italy, Japan, China ...

Crystallographic analysis of archaeal ribosomal protein L11 [PDF]

Acta Crystallographica Section F Structural Biology Communications, 2015
Ribosomal protein L11 is an important part of the GTPase-associated centre in ribosomes of all organisms. L11 is a highly conserved two-domain ribosomal protein. The C-terminal domain of L11 is an RNA-binding domain that binds to a fragment of 23S rRNA and stabilizes its structure. The complex between L11 and 23S rRNA is involved in the GTPase activity

Evidence for binary Smc complexes lacking kite subunits in archaea

IUCrJ, 2020
SMC complexes play a central role in chromosome organization in all domains of life. The bacterial Smc–ScpAB complex is a three-subunit complex composed of Smc, ScpA and ScpB.

Fidelity in Archaeal Information Processing [PDF]

, 2010
A key element during the flow of genetic information in living systems is fidelity. The accuracy of DNA replication influences the genome size as well as the rate of genome evolution.

Phylogenomics of prokaryotic ribosomal proteins. [PDF]

PLoS ONE, 2012
Archaeal and bacterial ribosomes contain more than 50 proteins, including 34 that are universally conserved in the three domains of cellular life (bacteria, archaea, and eukaryotes).

Crenarchaeal chromatin proteins Cren7 and Sul7 compact DNA by inducing rigid bends [PDF]

, 2012
Archaeal chromatin proteins share molecular and functional similarities with both bacterial and eukaryotic chromatin proteins. These proteins play an important role in functionally organizing the genomic DNA into a compact nucleoid.
