Transmembrane channel formation in rhodopsin-containing bilayer membranes
Abstract
Rhodopsin has been incorporated into planar lipid bilayer membranes. The effect of light is to increase the bilayer permeability in a pattern consistent with the formation of a transmembrane channel of about 10 A diameter. A model of visual excitation based on a light-activated and voltage-sensitive channel is presented.
