Crystal structure of Cruxrhodopsin-3 from Haloarcula vallismortis. [PDF]
PLoS ONE, 2014 Cruxrhodopsin-3 (cR3), a retinylidene protein found in the claret membrane of Haloarcula vallismortis, functions as a light-driven proton pump. In this study, the membrane fusion method was applied to crystallize cR3 into a crystal belonging to space ...

Species Widely Distributed in Halophilic Archaea Exhibit Opsin-Mediated Inhibition of Bacterioruberin Biosynthesis [PDF]
Journal of Bacteriology, 2019 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.

Effects of bio-based solvents on bacterioruberin stability and spectroscopic properties
Spectrochimica Acta Part A: Molecular and Biomolecular SpectroscopyBacterioruberin is a rare C50 xanthophyll carotenoid with exceptional antioxidant activity and scalable microbial bioproduction, making it a promising candidate for food, pharmaceutical, and biotechnological applications. However, the effect of solvents on its photophysical properties and stability remains poorly understood, limiting insight into its ...

Protective Roles of Bacterioruberin and Intracellular KCl in the Resistance of Halobacterium salinarium against DNA-damaging Agents. [PDF]
Journal of Radiation Research, 1998 Halobacterium salinarium, a member of the extremely halophilic archaebacteria, contains a C50-carotenoid namely bacterioruberin. We have previously reported the high resistance of this organism against the lethal actions of DNA-damaging agents including ionizing radiation and ultraviolet light (UV).

Microbiology, 1989 SUMMARY: Halobacterium cutirubrum was cultured in a complex medium designed for extreme halophiles containing 4 M-NaCl in the absence or presence of bacitracin (7, 14 or 28 μM) with shaking at 37°C for 24 h. Bacitracin at 7 or 14 μM inhibited growth (50% and 100%, respectively), phospholipid synthesis (88% and 96%, respectively) and bacterioruberin ...
