Crystallographic analysis of archaeal ribosomal protein L11 [PDF]

open access: yesActa 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]

open access: yesFEMS 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 ...

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

open access: yesFrontiers 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.

Archaeal chromatin proteins

open access: yesScience 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

Evidence for binary Smc complexes lacking kite subunits in archaea

open access: yesIUCrJ, 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.

Phylogenomics of prokaryotic ribosomal proteins. [PDF]

open access: yesPLoS 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).

Extended Archaeal Histone-Based Chromatin Structure Regulates Global Gene Expression in Thermococcus kodakarensis

open access: yesFrontiers in Microbiology, 2021
Histone proteins compact and organize DNA resulting in a dynamic chromatin architecture impacting DNA accessibility and ultimately gene expression. Eukaryotic chromatin landscapes are structured through histone protein variants, epigenetic marks, the ...

Archaeal S-Layers: Overview and Current State of the Art

open access: yesFrontiers in Microbiology, 2017
In contrast to bacteria, all archaea possess cell walls lacking peptidoglycan and a number of different cell envelope components have also been described.

Crystal structure of an archaeal CorB magnesium transporter

open access: yesNature Communications, 2021
CNNM/CorB proteins are a conserved family of membrane proteins associated with Mg2+ transport. Here, structures of an archaeal CorB protein in apo state and with Mg2+-ATP bound and accompanying biophysical experiments suggest direct Mg2+ transport by ...

DIVERSITY AND EVOLUTION OF TYPE IV PILI SYSTEMS IN ARCHAEA

open access: yesFrontiers in Microbiology, 2016
Many surface structures in archaea including various types of pili and the archaellum (archaeal flagellum) are homologous to bacterial type IV pili systems (T4P).
