Novel Glutamate–Putrescine Ligase Activity in Haloferax mediterranei: A New Function for glnA-2 Gene [PDF]

Biomolecules, 2021
The genome of the halophilic archaea Haloferax mediterranei contains three ORFs that show homology with glutamine synthetase (GS) (glnA-1, glnA-2, and glnA-3).

Advanced Strategies for Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) Production: PHA Synthase Homologous Overexpression in the Extremophile Haloferax mediterranei [PDF]

Marine Drugs
Bioplastics such as poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) are promising alternatives to conventional plastics. However, the high production cost limits their industrial application.

Analysis of Haloferax mediterranei Lrp Transcriptional Regulator. [PDF]

Genes (Basel), 2021
Haloferax mediterranei is an extremely halophilic archaeon, able to live in hypersaline environments with versatile nutritional requirements, whose study represents an excellent basis in the field of biotechnology. The transcriptional machinery in Archaea combines the eukaryotic basal apparatus and the bacterial regulation mechanisms.

Halolysin R4 of Haloferax mediterranei confers its host antagonistic and defensive activities. [PDF]

Appl Environ Microbiol, 2021
This study shows that halolysin R4 from Haloferax mediterranei provides its host antagonistic and defensive activities against other haloarchaea, which expands our knowledge of the traditional function of haloarchaeal extracellular proteases. Haloarchaeal extracellular serine proteases have been previously discussed

Replication Origin Deletion Enhances Poly(3-Hydroxybutyrate-co-3-Hydroxyvalerate) Synthesis in Haloarchaea

Microbiology Spectrum, 2022
Although the use of multiple replication origins for chromosome replication has been widely characterized in haloarchaea, whether it is possible to manipulate the chromosome copy number by their genetic engineering is not known, and how it would affect ...

Genomic stability in the archaeae Haloferax volcanii and Haloferax mediterranei [PDF]

Journal of Bacteriology, 1995
Through hybridization of available probes, we have added nine genes to the macrorestriction map of the Haloferax mediterranei chromosome and five genes to the contig map of Haloferax volcanii. Additionally, we hybridized 17 of the mapped cosmid clones from H. volcanii to the H. mediterranei genome. The resulting 35-point chromosomal comparison revealed

Deepening the knowledge of universal stress proteins in Haloferax mediterranei. [PDF]

Appl Microbiol Biotechnol
Abstract Haloarchaea, like many other microorganisms, have developed defense mechanisms such as universal stress proteins (USPs) to cope with environmental stresses affecting microbial growth. Despite the wide distribution of these proteins in Archaea, their biochemical characteristics still need to be discovered, and there ...

Carotenoids as a Protection Mechanism against Oxidative Stress in Haloferax mediterranei. [PDF]

Antioxidants (Basel), 2020
Haloarchaea are extremophilic microorganisms that in their natural ecosystem encounter several sources of oxidative stress. They have developed different strategies to cope with these harsh environmental conditions, among which bacterioruberin production is a very notable strategy.
