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

Archaea Signal Recognition Particle Shows the Way
Archaea SRP is composed of an SRP RNA molecule and two bound proteins named SRP19 and SRP54. Regulated by the binding and hydrolysis of guanosine triphosphates, the RNA‐bound SRP54 protein transiently associates not only with the hydrophobic signal sequence as it emerges from the ribosomal exit tunnel, but also interacts with the membrane‐associated ...

Lipids of the ultra‐thin square halophilic archaeon Haloquadratum walsbyi
The lipid composition of the extremely halophilic archaeon Haloquadratum walsbyi was investigated by thin‐layer chromatography and electrospray ionization‐mass spectrometry. The analysis of neutral lipids showed the presence of vitamin MK‐8, squalene, carotene, bacterioruberin and several retinal isomers.

C-50 carotenoids extracted from Haloterrigena thermotolerans strain K15: antioxidant potential and identification [PDF]
Halophilic archaea are one of the microorganism groups that have adapted to living in high saline environments and are important in terms of their potential use in biotechnology industry. One of the most important compounds they have, carotenoid, is used

Species Widely Distributed in Halophilic Archaea Exhibit Opsin-Mediated Inhibition of Bacterioruberin Biosynthesis [PDF]
All organisms use a variety of mechanisms to allocate limited resources to match their needs in their current environment. Here, we explore how halophilic microbes use a novel mechanism to allow efficient production of rhodopsin, a complex of an opsin protein and a retinal prosthetic group.

Data_Sheet_1_Complex Effects of Cytochrome P450 Monooxygenase on Purple Membrane and Bacterioruberin Production in an Extremely Halophilic Archaeon: Genetic, Phenotypic, and Transcriptomic Analyses.ZIP [PDF]
Halophilic archaea are known to produce a diverse array of pigments for phototrophy and photoprotection. The aim of this paper was to determine the role of a Halobacterium gene encoding the predicted cytochrome P450 monooxygenase (CYP174A1) in pigment ...
