metarhodopsin II

G-protein-coupled receptors (GPCRs) are seven transmembrane helix (TM) proteins that transduce signals into living cells by… (More)

In the G-protein-coupled receptor (GPCR) rhodopsin, the inactivating ligand 11-cis-retinal is bound in the seven-transmembrane… (More)

Isomerization of the 11-cis retinal chromophore in the visual pigment rhodopsin is coupled to motion of transmembrane helix H6… (More)

Rhodopsin is the prototypical G protein-coupled receptor, responsible for detection of dim light in vision. Upon absorption of a… (More)

Vertebrate rhodopsin consists of the apoprotein opsin and the chromophore 11-cis-retinal covalently linked via a protonated… (More)

An increase in fluorescence is observed upon light activation of bovine rhodopsin. The rate of increase is monoexponential (t1/2… (More)

A method was developed to measure Fourier-transform infrared (FTIR) difference spectra of detergent-solubilized rhodopsin… (More)

Rhodopsin is a retinal protein and a G-protein-coupled receptor; it shares with both of these families the seven helix structure… (More)

The resonance Raman spectra of bovine metarhodopsin I and metarhodopsin II have been measured. The spectra are compared with… (More)

Light isomerizes the chromophore of rhodopsin, 11-cis retinal (formerly retinene), to the all-trans configuration. This… (More)
