Rhodopsin photocascade

This LaTeX document generates a figure of the conformational changes in Rhodopsin following absorption of a photon(hV). Following absorption of light, the 11-cis-retinal chromophore isomerizes to the all-trans configuration within 200 fs and then relaxes thermally through a series of spectrally well-defined intermediates to the active Meta II state, which binds and activates the G protein transducin. Hydrolysis of the Schiffs base linkage generates opsin and frees all-trans retinal. BSI blue light sensitive intermediate. Adapted from Smith (2010)
