Bacterioopsin-Mediated Regulation of Bacterioruberin Biosynthesis in Halobacterium salinarum [PDF]

Journal of Bacteriology, 2011
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

Bacterioruberin (C₅₀ Carotenoid): Nutritional and Biomedical Potential of a Microbial Pigment. [PDF]

Nutrients
Haloarchaea are moderate and extreme halophilic microorganisms inhabiting hypersaline environments characterised by high ionic and oxidative stress due to extremely high salt concentrations and high incidence of UV radiation (mainly in spring and summer).

Microbial Bacterioruberin: A Comprehensive Review [PDF]

Indian Journal of Microbiology
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.

In Situ Study of the Function of Bacterioruberin in the Dual‐Chromophore Photoreceptor Archaerhodopsin‐4 [PDF]

Angewandte Chemie International Edition, 2018
AbstractWhile certain archaeal ion pumps have been shown to contain two chromophores, retinal and the carotenoid bacterioruberin, the functions of bacterioruberin have not been well explored. To address this research gap, recombinant archaerhodopsin‐4 (aR4), either with retinal only or with both retinal and bacterioruberin chromophores, was ...

Identification of carotenoids from the extremely halophilic archaeon Haloarcula japonica [PDF]

Frontiers in Microbiology, 2014
The carotenoids produced by extremely halophilic archaeon Haloarcula japonica were extracted and identified by their chemical, chromatographic, and spectroscopic characteristics (UV-Vis and mass spectrometry).

Antioxidative and chaperone-like activities of a bacterioruberin-rich extract: An innovative approach to protect the skin proteome. [PDF]

Int J Cosmet Sci
Abstract Objective Oxidative stress and its induced protein alterations are instrumental in the early onset and progression of ageing. To protect the skin proteome, we evaluated the extract of a bacterium isolated from snowflakes ( Arthrobacter ...
