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 ...

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.

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).

Microbial bacterioruberin: The new C50 carotenoid player in food industries
Food MicrobiologyThe demand for natural products has significantly increased, driving interest in carotenoids as bioactive compounds for both human and animal consumption. Carotenoids, natural pigments with several biological properties, like antioxidant and antimicrobial, are increasingly preferred over synthetic colorants by the consumers (chemophobia).

Ultrafast photochemistry of pharaonis halorhodopsin (p-HR) in the intact membrane of Natronomonas pharaonis has been studied by photoselective femtosecond pump-hyperspectral probe spectroscopy with high time resolution. Two variants of this sample were studied, one with wild-type retinal prosthetic groups and another after shifting the retinal ...

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.

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.
