Application of Raman Spectroscopy to Retinal Proteins
Raman spectroscopic studies on photoreactive retinal proteins are comprehensively described, including the basic physics of Raman scattering and illustrative examples of the types of information on… Expand
Kinetic resonance Raman studies reveal different conformational states of bacteriorhodopsin.
Resonance Raman study of intermediates of the halorhodopsin photocycle
The resonance Raman (RR) study of the retinal protein halorhodopsin (HR578) was extended to two of its photoproducts: HR and HRL 410 RR spectra of both species were recorded in H2O and D2O and… Expand
Photochemical quantum yield of bacteriorhodopsin from resonance Raman scattering as a probe for photolysis.
Abstract Bacteriorhodopsin (BR) is a retinal-binding protein in the purple membrane of Halobacteria where it acts as a light-driven proton pump. The quantum yield, γ B , of the primary photoreaction… Expand
Time and pH dependence of the L-to-M transition in the photocycle of bacteriorhodopsin and its correlation with proton release.
The pH dependence of the L-to-M transition in the photocycle of bacteriorhodopsin was studied in pump-probe resonance Raman (RR) flow experiments in the range pH 3.5-7.8 on a time scale of 0-700… Expand
Sensory rhodopsin I photocycle intermediate SRI380 contains 13‐cis retinal bound via an unprotonated Schiff base
Sensory rhodopsin I (SRI), the mutated derivative SRI‐D76N and the complex of SRI with its transducer HtrI were overexpressed in Halobacterium salinarium and analyzed by resonance Raman spectroscopy.… Expand

The photocycle of bacteriorhodopsin (bR) was studied at ambient temperature in aqueous suspensions of purple membranes using time-resolved resonance Raman (RR) and optical transient spectroscopy… Expand
Structure of the retinal chromophore in halorhodopsin
Resonance Raman (RR) spectra of the light‐driven chloride pump halorhodopsin (HR) were recorded after isolation of the protein from cell membranes of Halobacterium halobium. The spectra of the… Expand
