Deskripsi

Rhodopsin signalling is triggered by the light-induced isomerization of its 11-cisretinal chromophore. Here, the authors use NMR spectroscopy to define retinal orientation and interactions in the active metarhodopsin II intermediate, proposing a two-stage mechanism for rhodopsin activation.
