Role of Thr82 for the unique photochemistry of TAT rhodopsin
Marine bacterial TAT rhodopsin possesses the pKa of the retinal Schiff base, the chromophore, at neutral pH, and photoexcitation of the visible protonated state forms the isomerized 13-cis state, but reverts to the original state within 10–5 sec.

Chimeric proton-pumping rhodopsins containing the cytoplasmic loop of bovine rhodopsin. [PDF]
G-protein-coupled receptors (GPCRs) transmit stimuli to intracellular signaling systems. Rhodopsin (Rh), which is a prototypical GPCR, possesses an 11-cis retinal.

Biochemische und biophysikalische Charakterisierung von Rhodopsin-Guanylylzyklasen [PDF]
Rhodopsin-Guanylylzyklasen (RhGC) sind einzigartige Photorezeptoren, die kürzlich in Pilzen der Abteilung Blastocladiomycota entdeckt wurden [1]. RhGCs gehören zu den Enzym-Rhodopsinen und die Licht-sensitive mikrobielle Rhodopsin Domäne ist kovalent mit

Amino acid alignment of microbial rhodopsin and heliorhodopsin.
Multiple sequence alignments of microbial rhodopsins and heliorhodopsins were aligned using MUSCLE. Helices of AbHeR were based on the 3D structure (PDB: 6su3.1.A), which was predicted using the Swiss-Model.

Light-promoted rhodopsin expression and starvation survival in the marine dinoflagellate Oxyrrhis marina. [PDF]
The discovery of microbial rhodopsins in marine proteobacteria changed the dogma that photosynthesis is the only pathway to use the solar energy for biological utilization in the marine environment.

Light-driven Proton Pumps as a Potential Regulator for Carbon Fixation in Marine Diatoms
Diatoms are a major phytoplankton group responsible for approximately 20% of carbon fixation on Earth. They perform photosynthesis using light-harvesting chlorophylls located in plastids, an organelle obtained through eukaryote-eukaryote endosymbiosis ...

Mechanism divergence in microbial rhodopsins
A fundamental design principle of microbial rhodopsins is that they share the same basic light-induced conversion between two conformers. Alternate access of the Schiff base to the outside and to the cytoplasm in the outwardly open "E" conformer and cytoplasmically open "C" conformer, respectively, combined with appropriate timing of pKa changes ...

A large geometric distortion in the first photointermediate of rhodopsin, determined by double-quantum solid-state NMR [PDF]
Double-quantum magic-angle-spinning NMR experiments were performed on 11,12-C-13(2)-retinylidene-rhodopsin under illumination at low temperature, in order to characterize torsional angle changes at the C11-C12 photoisomerization site.

Assembly of Natively Synthesized Dual Chromophores Into Functional Actinorhodopsin
Microbial rhodopsin is a simple solar energy-capturing molecule compared to the complex photosynthesis apparatus. Light-driven proton pumping across the cell membrane is a crucial mechanism underlying microbial energy production. Actinobacteria is one of
