Understanding the tolerance of halophilic archaea to stress landscapes

Environmental Microbiology Reports, Volume 16, Issue 6, December 2024.
The tolerance responses of nine Haloarchaea species were analysed under 70 different conditions, including various salinities, temperatures, oxidative stress and the presence of metals. In general, all characterised species tolerated heavy metals, with a particularly striking tolerance to lithium. These results highlight the relevance of Haloarchaea in

Identification and codon reading properties of 5-cyanomethyl uridine, a new modified nucleoside found in the anticodon wobble position of mutant haloarchaeal isoleucine tRNAs [PDF]

, 2013
Most archaea and bacteria use a modified C in the anticodon wobble position of isoleucine tRNA to base pair with A but not with G of the mRNA. This allows the tRNA to read the isoleucine codon AUA without also reading the methionine codon AUG.

tsRNAs: A Prospective, Effective Therapeutic Intervention for Neurodegenerative Diseases

CNS Neuroscience &Therapeutics, Volume 30, Issue 12, December 2024.
Transfer RNA‐derived small RNAs (tsRNAs) are generated through the cleavage of transfer RNAs. tsRNAs modulate gene expression through transcriptional and translational mechanisms. tsRNAs are implicated in the pathogenesis of neurodegenerative disorders.

Analysis of multiple haloarchaeal genomes suggests that the quinone-dependent respiratory nitric oxide reductase is an important source of nitrous oxide in hypersaline environments [PDF]

, 2017
Microorganisms, including Bacteria and Archaea, play a key role in denitrification, which is the major mechanism by which fixed nitrogen returns to the atmosphere from soil and water.

Ploidy levels in diverse picocyanobacteria from the Baltic Sea

Environmental Microbiology Reports, Volume 16, Issue 5, October 2024.
The study on ploidy in brackish picocyanobacteria reveals minimal variation in genome copy numbers. Most strains are haploid, with a few oligoploid strains (two to four genome copies). The ploidy levels in brackish strains are lower compared to freshwater strains and more similar to marine strains. Abstract In nature, the number of genome or chromosome

N-glycosylation in the thermoacidophilic archaeon Sulfolobus acidocaldarius involves a short dolichol pyrophosphate carrier [PDF]

, 2016
N-glycosylation is a post-translational modification that occurs across evolution. In the thermoacidophilic archaea Sulfolobus acidocaldarius, glycoproteins are modified by an N-linked tribranched hexasaccharide reminiscent of the N-glycans assembled in ...

Bacterioruberin extract from Haloarchaea Haloferax marinum: Component identification, antioxidant activity and anti‐atrophy effect in LPS‐treated C2C12 myotubes

Microbial Biotechnology, Volume 17, Issue 9, September 2024.
The composition of C50 carotenoid bacterioruberin and its derivatives were identified in halophilic archaea Haloferax marinum MBLA0078, which exhibit potent antioxidant properties and protect against lipopolysaccharide‐induced C2C12 myotube atrophy, possibly through Akt/mTOR pathway activation, indicating their potential as natural antioxidants and ...

Developing a genetic manipulation system for the Antarctic archaeon, Halorubrum lacusprofundi: Investigating acetamidase gene function [PDF]

, 2016
© 2016 The Author(s). No systems have been reported for genetic manipulation of cold-adapted Archaea. Halorubrum lacusprofundi is an important member of Deep Lake, Antarctica (∼10% of the population), and is amendable to laboratory cultivation.

Transcriptomic evidence for an energetically advantageous relationship between Syntrophomonas wolfei and Methanothrix soehngenii

Environmental Microbiology Reports, Volume 16, Issue 3, June 2024.
We studied predefined co‐cultures to investigate the influence of acetate scavenger Methanothrix soehngenii on butyrate oxidation by a co‐culture of Syntrophomonas wolfei and Methanospirillum hungatei. RNAseq was used to compare the gene expression profiles of syntroph S. wolfei with and without the presence of the acetate scavenger M.
