The C50 carotenoid bacterioruberin regulates membrane fluidity in pink-pigmented Arthrobacter species [PDF]
Archives of Microbiology, 2021 AbstractCarotenoids have several crucial biological functions and are part of the cold adaptation mechanism of some bacteria. Some pink-pigmented Arthrobacter species produce the rare C50 carotenoid bacterioruberin, whose function in these bacteria is unclear and is found mainly in halophilic archaea.

Hydroxyl radical scavenging ability of bacterioruberin
Radiation Physics and Chemistry, 1997Abstract A red carotenoid pigment, bacterioruberin, was extracted from Rubrobacter radiotolerans. The OH scavenging effect of this pigment was studied using a system of thymine degradation and compared with those of cysteine and β-carotene. Thymine solution (5 × 10−4 mol/dm3 with 0.2% SDS buffered at pH 7.0) was irradiated with 60Co γ-rays in the ...

Structural Role of Bacterioruberin in the Trimeric Structure of Archaerhodopsin-2
Journal of Molecular Biology, 2008Archaerhodopsin-2 (aR2), a retinal protein-carotenoid complex found in the claret membrane of Halorubrum sp. aus-2, functions as a light-driven proton pump. In this study, the membrane fusion method was utilized to prepare trigonal P321 crystals (a=b=98.2 A, c=56.2 A) and hexagonal P6(3) crystals (a=b=108.8 A, c=220.7 A).

Bacterioruberin is a red-pigmented C50 carotenoid commonly found in halophilic archaea, known for its strong antioxidant properties. In this study, we demonstrate the complete biosynthesis of bacterioruberin in metabolically engineered Corynebacterium glutamicum overproducing lycopene.

Bacterioruberins Reinforce Reconstituted Halobacterium Lipid Membranes
1991We have developed methodologies for the determination of the topology of α,ω-dihydroxylated carotenoids incorporated into vesicles and for the evaluation of the reinforcing effects of these carotenoids on lipid bilayers.

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2013
Laboratory cultures of a number of red extremely halophilic Archaea (Halobacterium salinarum strains NRC-1 and R1, Halorubrum sodomense, Haloarcula valismortis) and of Salinibacter ruber, a red extremely halophilic member of the Bacteria, have been investigated by Raman spectroscopy using 514.5nm excitation to characterize their carotenoids.

Bioresource Technology
Bacterioruberin is widely used in medicine, food, and cosmetics owing to its prominent characteristics of antioxidants and bioactivities. Bioconversion of methane into bacterioruberin is a promising way to address biomanufacturing substrate costs and greenhouse gas emissions but has not been achieved yet.

Halorhodopsin is a retinal protein with a seven-transmembrane helix and acts as an inward light-driven Cl(-) pump. In this study, structural state of the solubilized halorhodopsin (NpHR) from the biomembrane of mutant strain KM-1 of Natronomonas pharaonis in nonionic detergent was investigated.
