Acetabularia-Rhodopsin, eine lichtgetriebene Protonenpumpe aus einem autotrophen Eukaryoten
Ein Rhodopsin aus Acetabularia acetabulum (AR) wird mit molekulargenetischen und elektrophysiologischen Mitteln charakterisiert. Mithilfe der reversen Transkription und der Polymerasekettenreaktion wurde auf der Grundlage einer veröffentlichten, unvollständigen Sequenz, das gesamte Transkript eines …

Photochemical Studies of Rhodopsin, Purple Membrane, and Their Analogues
Rhodopsin and analogues. The absorption spectrum of the bathoproduct of rhodopsin, which contains 11-cis retinal as chromophore, is obtained at 77(DEGREES) K under the condition that on the average less than one photon can be absorbed by each rhodopsin molecule. The spectrum, with (lamda)(,max) at …

Noninvasive optical inhibition with a red-shifted microbial rhodopsin
… and implementation of a new red-shifted cruxhalorhodopsin, Jaws, derived from Haloarcula salinarum (strain Shark), which mediates three-fold higher red light-induced photocurrents than other inhibitory opsins. I describe the design process involved in engineering Jaws, as well as its …

Solid-state nuclear magnetic resonance of rhodopsin and its photointermediates
… of the membrane-bound light receptor protein rhodopsin leads<br/>to a highly energetic species called bathorhodopsin, which is stable at temperatures<br/>below 125 K. Bathorhodopsin stores about 2/3 of the absorbed photon energy but<br/>the mechanisms with which this energy is stored is not …

Structure-function relationship of archaeal rhodopsin proteins analyzed by continuum electrostatics
Rhodopsin proteins perform two cellular key functions: signaling of external stimuli and ion transport. Examples of both functional types are found in the family of archaeal rhodopsins, namely the proton pump bacteriorhodopsin, the chloride pump halorhodopsin and the photoreceptor sensory rhodopsin …

Polarisationsabhängige FTIR-Spektroskopie : strukturelle Untersuchungen an den Proteinen Bakteriorhodopsin und Rhodopsin
… lichtinduzierten Reaktion der Proteine Bakteriorhodopsin und Rhodopsin untersucht. Die Absorption von Licht durch das optisch aktive Zentrum initiiert in beiden Systemen molekulare Veränderungen, welche die spezifische Funktion und nachfolgende physiologische Stoffwechselreaktionen auslösen. …

Characterisation of Rhodopsin Retinitis Pigmentosa mutants located in Intradiscal Loop 1
… are several hundred RP mutations associated with rhodopsin, a photosensitive GPCR pigment found within rod cells of the retina. Previous studies have shown that many rhodopsin RP mutants fold incorrectly or affect protein stability. This study investigates the effect of three RP mutants located in …

Infrared studies of rhodopsin and its low temperature photoproducts, bathorhodopsin and isorhodopsin
… that change in position and intensity between rhodopsin and the photoproducts formed at low temperature (70K), bathorhodopsin and isorhodopsin. A method has been developed to obtain infrared difference spectra between rhodopsin and bathorhodopsin, bathorhodopsin and isorhodopsin, and rhodopsin …

FTIR Spectroscopy of the photophobic sensory rhodopsin II/transducer complex from natronabacterium pharaonis
Archaebakterielles Sensory Rhodopsin besitzt eine transmembrane Struktur bestehend aus sieben alpha Helices. Als Chromophor dient ein Retinalmolekül, das über eine protonierte Schiff´sche Base an das Protein gebunden ist. Dieses System ist exemplarisch für Signal Transduktion und stieß in den …

Characterisation of Truncated Mutant Rhodopsin and its Involvement in the Pathogenesis of Retinitis Pigmentosa
… 20-25% of cases are caused by mutations in the rhodopsin gene. The mutations located in the N-terminus of rhodopsin produce severely misfolded protein, which has been shown to cleave at the N-terminus removing the glycosylation sites(Tam & Moritz, 2007),(Krebs, et al., 2010). We aimed to further …

Structural and Biophysical Characterisation of Denatured States and Reversible Unfolding of Sensory Rhodopsin II
… the kinetics for reversible unfolding of sensory rhodopsin II (pSRII), a retinal-binding photophobic receptor from Natronomonas pharaonis. pSRII is difficult to denature, and only SDS can dislodge the retinal chromophore without rapid aggregation. Even in 30% SDS (0.998 $\mathit{\Chi}_{SDS}$), …

Functional analysis of A 5' untranslated variant in rhodopsin : implications for the retinitis pigmentosa phenotype
… are frequently observed in RP. Mutations in Rhodopsin (RHO) have been identified as a major cause of RP. A sequence variant identified in the 5' untranslated region of RHO, g.269A>G, also known as c.-26A>G, was proposed to increase the risk of developing RP. In this study, the functional …
