Extremely halophilic archaea contain retinal-binding integral membrane proteins called bacteriorhodopsins that function as light-driven proton pumps. So far, bacteriorhodopsins capable of generating a chemiosmotic membrane potential in response to light have been demonstrated only in halophilic archaea. We describe here a type of rhodopsin derived from bacteria that was discovered through genomic analyses of naturally occuring marine bacterioplankton. The bacterial rhodopsin was encoded in the…

Functional characterization of flavobacteria rhodopsins reveals a unique class of light-driven chloride pump in bacteria
TLDR
The genome of the marine flavobacterium Nonlabens marinus S1-08T encodes three different types of rhodopsins, and functional analysis demonstrated that NM-R1 andNM-R2 are light-driven outward-translocating H+ and Na+ pumps, respectively, representing the first chloride-pumping r Rhodopsin uncovered in a marine bacterium.
Evidence of microbial rhodopsins in Antarctic Dry Valley edaphic systems
TLDR
The presence of several new putative H+ , Na+ and Cl+ pumping rhodopsins identified by metagenomic analysis of Antarctic desert hypolithic communities is shown and suggests a possible predominant function as heterotrophic energy supply proteins, a feasible microbial adaptation to the harsh conditions prevalent in Antarctic edaphic systems.
Functional expression of the eukaryotic proton pump rhodopsin OmR2 in Escherichia coli and its photochemical characterization
TLDR
A phylogenetically distinct eukaryotic rhodopsin from the dinoflagellate Oxyrrhis marina that can be expressed in E. coli cells is reported, indicating its functional expression.
Marine Bacterial and Archaeal Ion-Pumping Rhodopsins: Genetic Diversity, Physiology, and Ecology
TLDR
It is inferred from the distribution of rhodopsin genes in diverse genomic contexts that different marine bacteria probably use rhodopins to support light-dependent fitness strategies somewhere between these two extremes.
Microbial Halorhodopsins: Light-Driven Chloride Pumps.
TLDR
The functional and structural characteristics of halorhodopsins are described and the data is discussed in light of common principles underlying the mechanism of ion pumps and sensors and will review biophysical and biochemical aspects of neuronal silencers.
Light stimulates growth of proteorhodopsin-containing marine Flavobacteria
TLDR
The results show that the phototrophy conferred by proteorhodopsin can provide critical amounts of energy, not only for respiration and maintenance but also for active growth of marine bacterioplankton in their natural environment.
Anabaena Sensory Rhodopsin: A Photochromic Color Sensor at 2.0 Å
TLDR
Anabaena sensory rhodopsin exhibits light-induced interconversion between stable 13-cis and all-trans states of the retinylidene protein, thus providing a mechanism for a single protein to signal the color of light to regulate color-sensitive processes such as chromatic adaptation in photosynthesis.
Presence of a Haloarchaeal Halorhodopsin-Like Cl− Pump in Marine Bacteria
TLDR
Inward Cl−-pumping rhodopsin is present in genera of the class Cytophagia and may have the same evolutionary origins as haloarchaeal HR.
Cyanobacterial Light-Driven Proton Pump, Gloeobacter Rhodopsin: Complementarity between Rhodopsin-Based Energy Production and Photosynthesis
TLDR
The efficient proton pumping and rapid photocycle of GR strongly suggests that Gloeobacter rhodopsin functions as a proton Pumping in its natural environment, probably compensating the shortage of energy generated by chlorophyll-based photosynthesis without thylakoids.
A unique clade of light-driven proton-pumping rhodopsins evolved in the cyanobacterial lineage
TLDR
Results suggest that the CyR clade proteins evolved together with chlorophyll-based photosynthesis systems and may have been optimized for the cyanobacterial environment.

A eukaryotic protein, NOP-1, binds retinal to form an archaeal rhodopsin-like photochemically reactive pigment.
TLDR
Laser flash kinetic spectroscopy demonstrates that the retinal-reconstituted pigment undergoes a photochemical reaction cycle with a near-UV-absorbing intermediate that is similar to the M intermediates produced by transient Schiff base deprotonation of the chromophore in the photocycles of bacteriorhodopsin and sensory rhodopsins I and II.
Molecular mechanism of photosignaling by archaeal sensory rhodopsins.
TLDR
The SR-Htr signaling complexes allow studies of the biophysical chemistry of signal generation and relay, from the photobiophysics of initial excitation of the receptors to the final output at the level of the flagellar motor switch, revealing fundamental principles of sensory transduction.

TLDR
The results extend the eubacterial transducer family to the archaebacteria and substantiate the proposal that the methylated membrane protein functions as a signal-transducing relay between sensory rhodopsin I and cytoplasmic sensory-pathway components.

TLDR
The atomic structure of bacteriorhodopsin and the outlines of its proton transport mechanism are now available and the directionality of the translocation is ensured by the accessibility of the Schiff base to the extracellular and cytoplasmic directions after the retinal is photoisomerized.
Rhodopsin-like protein from the purple membrane of Halobacterium halobium.
TLDR
It is shown that the purple colour is due to retinal bound to an opsin-like protein, the only protein present in this membrane fragment, which has been isolated in relatively pure form from Halobacterium halobium.
The transducer protein HtrII modulates the lifetimes of sensory rhodopsin II photointermediates.
Structure of bacteriorhodopsin at 1.55 A resolution.
TLDR
The results indicate extensive involvement of bound water molecules in both the structure and the function of this seven-helical membrane protein.

Biochemical analysis of spontaneous fepA mutants of Escherichia coli.
TLDR
The variation in endpoints among the deletions argues against the involvement of a normal transposon in their formation and unexpected homology was found between enterobactin gene cluster DNA and lacPOZ and pSC101.
