A rapid change in an interfacial electric potential of isolated bovine rod outer segment disk membranes occurs upon illumination. This potential change, which has been detected by the use of spin-labeled hydrophobic ions, apparently occurs within a low dielectric boundary region of the membrane near the external (cytoplasmic) surface and is positive with respect to the aqueous exterior of the disk. The magnitude of the potential change is pH-and temperature-dependent and appears with a first-order half-time of approximately 7 ms at 21 degrees C. A simple model in which one positive charge per bleached rhodopsin is translocated from the cytoplasmic aqueous space into the membrane low dielectric boundary region readily accounts for all experimental observations. The great similarity of the boundary potential change to the R2 phase of the early receptor potential suggests that the two have the same molecular origin.
