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

Archaeal Chromatin Proteins Cren7 and Sul7d Compact DNA by Bending and Bridging
mBio, 2020 A long-standing question is how chromosomal DNA is packaged in Crenarchaeota, a major group of archaea, which synthesize large amounts of unique small DNA-binding proteins but in general contain no archaeal histones.

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.

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

Translocation of proteins across archaeal cytoplasmic membranes [PDF]
FEMS Microbiology Reviews, 2004 All cells need to transport proteins across hydrophobic membranes. Several mechanisms have evolved to facilitate this transport, including: (i) the universally-conserved Sec system, which transports proteins in an unfolded conformation and is thought to be the major translocation pathway in most organisms and (ii) the Tat system, which transports ...

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.

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).

Rings in the Extreme: PCNA Interactions and Adaptations in the Archaea [PDF]
, 2012 Biochemical and structural analysis of archaeal proteins has enabled us to gain great insight into many eukaryotic processes, simultaneously offering fascinating glimpses into the adaptation and evolution of proteins at the extremes of life. The archaeal

The archaeal protein SepF is essential for cell division in Haloferax volcanii
Nature Communications, 2021 In most bacteria, cell division depends on the tubulin homolog FtsZ and other proteins, such as SepF, that form a complex termed the divisome. Cell division also depends on FtsZ in many archaea, but other components of the divisome are unknown.
