Towards the Elucidation of Assimilative nasABC Operon Transcriptional Regulation in Haloferax mediterranei. [PDF]

Genes (Basel), 2021
The assimilatory pathway of the nitrogen cycle in the haloarchaeon Haloferax mediterranei has been well described and characterized in previous studies. However, the regulatory mechanisms involved in the gene expression of this pathway remain unknown in haloarchaea.

Production of an Extracellular Polysaccharide by Haloferax mediterranei [PDF]

Applied and Environmental Microbiology, 1988
The extremely halophilic archaebacterium Haloferax mediterranei produces an exocellular polymeric substance that gives the colonies a typical mucous character and is responsible for the appearance of a superficial layer in unshaken liquid medium.

Production of polyhydroxyalkanoates from hydrolysed rapeseed meal by Haloferax mediterranei

Bioresource Technology, 2023
Rapeseed meal (RSM) hydrolysate is a potential low-cost feedstock for the production of polyhydroxyalkanoates (PHAs) by the archaea, Haloferax mediterranei. Acidic and enzymatic hydrolysis were carried out to compare effectiveness. Enzymatic hydrolysis is more effective than acidic hydrolysis for fermentation substrate leading to increased PHA ...

Enoyl-CoA hydratase mediates polyhydroxyalkanoate mobilization in Haloferax mediterranei [PDF]

Scientific Reports, 2016
AbstractAlthough polyhydroxyalkanoate (PHA) accumulation and mobilization are one of the most general mechanisms for haloarchaea to adapt to the hypersaline environments with changeable carbon sources, the PHA mobilization pathways are still not clear for any haloarchaea.

Nitrogen regulation of protein–protein interactions and transcript levels of GlnK PII regulator and AmtB ammonium transporter homologs in Archaea [PDF]

, 2013
Gene homologs of GlnK PII regulators and AmtB-type ammonium transporters are often paired on prokaryotic genomes, suggesting these proteins share an ancient functional relationship.

Conserved substitution patterns around nucleosome footprints in eukaryotes and Archaea derive from frequent nucleosome repositioning through evolution. [PDF]

, 2013
Nucleosomes, the basic repeat units of eukaryotic chromatin, have been suggested to influence the evolution of eukaryotic genomes, both by altering the propensity of DNA to mutate and by selection acting to maintain or exclude nucleosomes in particular ...

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.

Effects of chaotropic salts on global proteome stability in halophilic archaea: Implications for life signatures on Mars

Environmental Microbiology, Volume 25, Issue 11, Page 2216-2230, November 2023., 2023
Abstract Halophilic archaea thriving in hypersaline environments, such as salt lakes, offer models for putative life in extraterrestrial brines such as those found on Mars. However, little is known about the effect of the chaotropic salts that could be found in such brines, such as MgCl2, CaCl2 and (per)chlorate salts, on complex biological samples ...

A haloarchaeal ferredoxin electron donor that plays an essential role in nitrate assimilation [PDF]

, 2011
In the absence of ammonium, many organisms, including the halophilic archaeon Haloferax volcanii DS2 (DM3757), may assimilate inorganic nitrogen from nitrate or nitrite, using a ferredoxin-dependent assimilatory NO3-/NO2- reductase pathway.

Analysis of Lsm Protein-Mediated Regulation in the Haloarchaeon Haloferax mediterranei. [PDF]

Int J Mol Sci
The Sm protein superfamily includes Sm, like-Sm (Lsm), and Hfq found in the Eukarya, Archaea, and Bacteria domains. Archaeal Lsm proteins have been shown to bind sRNAs and are probably involved in various cellular processes, suggesting a similar function in regulating sRNAs by Hfq in bacteria.
