Metallochaperones regulate intracellular copper levels. [PDF]

PLoS Computational Biology, 2013
Copper (Cu) is an important enzyme co-factor that is also extremely toxic at high intracellular concentrations, making active efflux mechanisms essential for preventing Cu accumulation. Here, we have investigated the mechanistic role of metallochaperones

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.

Characterization and Functional Evaluation of Carotenoids From Haloarcula rubripromontorii BS2

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
Fractionation and comprehensive characterization of C50 carotenoids from Haloarcula rubripromontorii BS2, identified all‐trans bacterioruberin as the predominant isomer. The haloarchaeal carotenoid exhibited strong antioxidant activity, photostability in oil and was biocompatible with human keratinocytes, highlighting their potential as sustainable ...

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

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.

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 ...

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.
