Helix Movement is Coupled to Displacement of the Second Extracellular Loop in Rhodopsin Activation
The second extracellular loop (EL2) of rhodopsin forms a cap over the binding site of its photoreactive 11-cis retinylidene chromophore. A critical question has been whether EL2 forms a reversible gate that opens upon activation or acts as a rigid barrier. Distance measurements using solid-state (13...
