Morphology of the archaellar motor and associated cytoplasmic cone in Thermococcus kodakaraensis [PDF]

, 2017
Archaeal swimming motility is driven by archaella: rotary motors attached to long extracellular filaments. The structure of these motors, and particularly how they are anchored in the absence of a peptidoglycan cell wall, is unknown.

A Spotlight on Archaea in Humans, Livestock and Poultry: A Review

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
The microbiota includes prokaryotes (archaea and bacteria) and eukaryotes. Archaea are single‐celled prokaryotes and essential part of gut microbiome. Researches on archaea in ruminants and humans are more than mono‐gastric. The low abundance of archaea in the gut depends on the method used (metagenomics or meta‐transcriptomic) and age of people or ...

Systems analysis of bioenergetics and growth of the extreme halophile Halobacterium salinarum. [PDF]

PLoS Computational Biology, 2009
Halobacterium salinarum is a bioenergetically flexible, halophilic microorganism that can generate energy by respiration, photosynthesis, and the fermentation of arginine.

Chromatin and gene regulation in archaea

Molecular Microbiology, Volume 123, Issue 3, Page 218-231, March 2025.
Recent data from diverse archaea with different repertoires of nucleoid‐associated proteins show a common genome‐wide chromatin organisation where chromatin maintains access to gene promoters independently of transcription activity. Abstract The chromatinisation of DNA by nucleoid‐associated proteins (NAPs) in archaea ‘formats’ the genome structure in ...

A Non‐Discriminating Aspartyl‐tRNA Synthetase fromHalobacterium salinarum [PDF]

RNA Biology, 2006
The tRNA-dependent transamidation pathway is the essential route for Asn-tRNA(Asn) formation in organisms that lack an asparaginyl-tRNA synthetase. This pathway relies on a nondiscriminating aspartyl-tRNA synthetase (ND-AspRS encoded by aspS), an enzyme with relaxed tRNA specificity, to form Asp-tRNA(Asn).

Regulation of translation in haloarchaea: 5'- and 3'-UTRs are essential and have to functionally interact in vivo [PDF]

, 2009
Recently a first genome-wide analysis of translational regulation using prokaryotic species had been performed which revealed that regulation of translational efficiency plays an important role in haloarchaea.

Archaeal Signalling Networks—New Insights Into the Structure and Function of Histidine Kinases and Response Regulators of the Methanogenic Archaeon Methanosarcina acetivorans

Environmental Microbiology, Volume 27, Issue 2, February 2025.
Methanosarcina acetivorans possesses extensive signal transduction systems, including 53 histidine kinases and 15, mainly REC‐only, response regulators. All recombinant versions of representative kinase types except MA_type 2 showed autokinase activity.

AglM and VNG1048G, Two Haloarchaeal UDP-Glucose Dehydrogenases, Show Different Salt-Related Behaviors

Life, 2016
Haloferax volcanii AglM and Halobacterium salinarum VNG1048G are UDP-glucose dehydrogenases involved in N-glycosylation in each species. Despite sharing >60% sequence identity and the ability of VNG1048G to functionally replace AglM in vivo, these ...

Genotypic and Lipid Analyses of Strains From the Archaeal Genus Halorubrum Reveal Insights Into Their Taxonomy, Divergence, and Population Structure [PDF]

, 2018
To gain a better understanding of how divergence occurs, and how taxonomy can benefit from studying natural populations, we isolated and examined 25 closely related Halorubrum strains obtained from different hypersaline communities and compared them to ...

The separation between mRNA‐ends is more variable than expected

FEBS Open Bio, Volume 14, Issue 12, Page 1985-1995, December 2024.
Both mRNA ends are in proximity despite mRNAs origin, length and secondary or tertiary structures. However, we show that the distance between native mRNA ends is not constant and varies across organisms. We found that native sequences show much larger variations than those observed in random sequences, implying the existence of a biological mechanism ...
