A New Era for Using Natural Pigments: The Case of the C<sub>50</sub> Carotenoid Called Bacterioruberin. [PDF]
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Complex Effects of Cytochrome P450 Monooxygenase on Purple Membrane and Bacterioruberin Production in an Extremely Halophilic Archaeon: Genetic, Phenotypic, and Transcriptomic Analyses [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 ...

Nebulized Bacterioruberin/Astaxanthin-Loaded Nanovesicles: Antitumoral Activity and Beyond. [PDF]
The membranes of halophilic archaea are a source of novel biomaterials, mainly of isoprenoid nature, with therapeutic properties practically unraveled. Here, we explored the antitumoral activity of neutral archaeolipids (NAs, such as bacterioruberin, astaxanthin, and dihydrosqualene) present in the total archaeolipids (TAs) (a fraction from the first ...

Bacterioopsin-Mediated Regulation of Bacterioruberin Biosynthesis in Halobacterium salinarum [PDF]
ABSTRACT Integral membrane protein complexes consisting of proteins and small molecules that act as cofactors have important functions in all organisms. To form functional complexes, cofactor biosynthesis must be coordinated with the production of corresponding apoproteins. To examine this coordination, we study bacteriorhodopsin

Microbial Bacterioruberin: A Comprehensive Review [PDF]
Bacterioruberin (BR) is a fat-soluble, dipolar, reddish pigment predominantly found in halophilic archaea. BR is a rare C50 carotenoid from the xanthophyll family, and it has been extensively studied for its potent antioxidant properties, such as its ability to protect cells from oxidative stress.
