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

Early evolution of purple retinal pigments on Earth and implications for exoplanet biosignatures

, 2018
We propose that retinal-based phototrophy arose early in the evolution of life on Earth, profoundly impacting the development of photosynthesis and creating implications for the search for life beyond our planet.

Identification of a system required for the functional surface localization of sugar binding proteins with class III signal peptides in Sulfolobus solfataricus [PDF]

, 2007
The hyperthermophilic archaeon Sulfolobus solfataricus contains an unusual large number of sugar binding proteins that are synthesized as precursors with a class III signal peptide.

Phenotypic Characterization of Pectinase‐Producing Alkaliphilic Microbial Isolates From Lake Bogoria, Baringo County, Kenya

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
Four alkaliphilic microbial isolates were screened, and all were found to produce alkaline pectinases. All the pectinase‐producers were identified as Bacillus halodurans. ABSTRACT Alkaline pectinases are in demand in industrial processes that require the degradation of plant pectins at high pH, for example, removal of pectin stains from fabrics ...

Identification of microorganism belonging to the Halobacteriaceae family in the salt mine of Zipaquirá, Cundinamarca, Colombia

Acta Biológica Colombiana, 2004
This study was designed to identified halophytus microorganisms on samples from the salt mines of Zipaquirá, Colombia. We identified two representative genre Halobacterium sp. and Halococcus sp. which grew at an optimal NaCl concentration of 2.5 M.

Microarray analysis in the archaeon Halobacterium salinarum strain R1.

PLoS ONE, 2007
BackgroundPhototrophy of the extremely halophilic archaeon Halobacterium salinarum was explored for decades. The research was mainly focused on the expression of bacteriorhodopsin and its functional properties.

Structure determination of the phosphatidylglycerosulfate (diether analog) from Halobacterium cutirubrum

Journal of Lipid Research, 1973
A novel phosphosulfolipid has been isolated as the potassium salt from the extremely halophilic bacterium Halobacterium cutirubrum; its molecular formula was established as C46H93PSK2.

Genome-wide analysis of growth phase-dependent translational and transcriptional regulation in halophilic archaea : research article [PDF]

, 2007
Background Differential expression of genes can be regulated on many different levels. Most global studies of gene regulation concentrate on transcript level regulation, and very few global analyses of differential translational efficiencies exist.

Integration of photosensory signals in Halobacterium halobium [PDF]

Journal of Bacteriology, 1986
Stimulation of Halobacterium halobium through its sensory photosystems, PS 370 and PS 565, leads either to a prolonged or to a shortened interval between two reversals of the swimming direction of the cell, the attractant or repellent response. Stimuli are integrated to yield the same response regardless through which photosystem they are given ...

Isolation and Characterisation of Bacteria From an Extremely High Boron and Salinity‐Tolerant Puccinellia distans (Jacq.) Parl. Rhizosphere and Their Potential Impact on the Growth of Bread Wheat (Triticum aestivum L.)

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Under greenhouse conditions, the boron‐tolerant bacterium Pseudomonas poae demonstrated a significant enhancement in wheat growth under boron‐induced stress. These findings highlight its promising role as a sustainable biofertiliser to bolster crop productivity in boron‐affected agroecosystems.
