Halobacterium salinarum nom. corrig., a Name To Replace Halobacterium salinarium (Elazari-Volcani) and To Include Halobacterium halobium and Halobacterium cutirubrum [PDF]

International Journal of Systematic Bacteriology, 1996
The specific epithet of Halobacterium salinarium is a grammatically incorrect form for the genitive of salinae (salt works). Therefore, we propose that the name of the type species of the genus Halobacterium should be changed to Halobacterium salinarum nom. corrig.

A Two‐Protein Chemoreceptor Complex Regulates Oxygen Thresholds in Bacterial Magneto‐Aerotaxis

Advanced Science, Volume 12, Issue 34, September 11, 2025.
Magnetotactic bacteria align with Earth's magnetic field, helping them migrate toward low‐oxygen environments. This study reveals how Magnetospirillum gryphiswaldense uses a specialized flavin adenine dinucleotide (FAD)‐dependent chemoreceptor, composed of two interacting proteins, for precise navigation in oxygen gradients.

The Biosynthesis of the Pyrimidine Moiety of Thiamin in Halobacterium salinarum.

Journal of nutritional science and vitaminology, 2016
The biosynthetic pathway of the pyrimidine moiety of thiamin was studied in the archaean Halobacterium salinarum. Thiamin is biosynthesized from 4-amino-5-hydroxymethyl-2-methylpyrimidine (pyrimidine) and 5-(2-hydroxyethyl)-4-methylthiazole (thiazole). The pyrimidine and the thiazole are biosynthesized de novo in microorganisms. The biosynthetic routes

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.

Identification of the arginine/ornithine antiporter ArcD from Halobacterium salinarum [PDF]

FEBS Letters, 2008
This paper identifies the first arginine/ornithine antiporter ArcD from the domain of archea. The functional role of ArcD is demonstrated by transport assays with radioactive labelled arginine, by its necessity to enable arginine fermentation under anaerobic growth conditions and by the consumption of arginine from the medium during growth.

Two Decades of Optogenetic Tools: A Retrospective and a Look Ahead

Advanced Genetics, Volume 6, Issue 3, September 2025.
Optogenetics provides up to millisecond scale, cell type‐specific control of biology using light‐sensitive proteins. This review chronicles two decades of tool development, from microbial rhodopsins and photoactivated enzymes to allosteric switches, surveys broad applications in neuroscience, molecular and cell biology, cardiology, immunology, and ...

A conserved transcription factor controls gluconeogenesis via distinct targets in hypersaline-adapted archaea with diverse metabolic capabilities.

PLoS Genetics
Timely regulation of carbon metabolic pathways is essential for cellular processes and to prevent futile cycling of intracellular metabolites. In Halobacterium salinarum, a hypersaline adapted archaeon, a sugar-sensing TrmB family protein controls ...

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.

Phosphate-Dependent Behavior of the ArchaeonHalobacterium salinarumStrain R1 [PDF]

Journal of Bacteriology, 2009
ABSTRACTPhosphate is essential for life on earth, since it is an integral part of important biomolecules. The mechanisms applied by bacteria and eukarya to combat phosphate limitation are fairly well understood. However, it is not known how archaea sense phosphate limitation or which genes are regulated upon limitation.

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 ...
