Phosphorylation of Frog Photoreceptor Membranes induced by Light

Abstract

LIGHT induces changes in the visual pigment rhodopsin and its retinaldehyde prosthetic group1 but the specific chemical events which lead to photoreceptor excitation remain obscure. We describe here a phosphorylation reaction initiated by rhodopsin bleaching which may be part of the mechanism linking photon absorption to changes in membrane resistance.
